General Help

Determining which items on the graph can be moved.

All moveable items on a given graph will be represented on the right in the palette. When using the shifter tool or endpoint mover tool, these icons will always be greyed-out, meaning that the moveable items are already given to you on the graph.

Selecting objects for more information

Sometimes selecting a point on the graph will reveal its coordinates. Note that the coordinates do not take the units on the axes into account.

Grey lines on the graph

After you have adjusted the position of a shiftable line or a point, the location of the original line will be represented by a grayed-out version of the original. Sometimes, you will need to plot more than one line, point, or curve. The original element will remain in its original color state on the palette until you have plotted all the lines, points, curves. After you’ve positioned the maximum number of lines, points, or curves, each element on the palette will turn grey.

Adding a point

Select and drag a point onto the graph.

Moving a point

Select and drag a point on the graph from one location to another.

Deleting a point

Select and drag a point off of the graph.

Occasionally points will also contain drop lines that automatically extend to one or both axes.

Connected Points

Placing a set of connected points.

Each point within a set of connected points must be selected and dragged on to the graph individually, and will be automatically connected to the previously added point. Be sure to add the points in the correct order, as this affects the shape of the line and thus how the object is graded.

Moving a set of connected points

Select and drag any point along the connected points line from one location to another. Note that you cannot move the entire curve without changing its shape (as with line segments).

Removing a set of connected points

Select and drag each point from the line off of the graph.

Line Segments

Creating a line segment.

Line segments are connected by two points. To place a line segment, select and drag a point with a tail onto the graph. Next, select and drag another point with a tail onto the graph. A line will connect these two points.

Splitting up a line segment

Existing line segments can be split up. Select and drag a point with a tail onto the graph and position it so that the two points that are connected by the existing line segment are highlighted. The old line segment will be removed and two new line segments will be created.

Adjusting the position of a line segment

Select and drag a point that is connected by a line segment from one location to another. Selecting any part of a line except the two points, on the graph may reveal additional information.

Deleting a line segment

Select and drag a point from the segment off of the graph.

Placing a line

Select and drag a line onto the graph.

Moving a line

Select and drag any part of the line except the two points from one location to another.

Adjusting the slope of a line

Once the line is on the graph, select and drag one of the two points on the line from one location to another.

Finding the slope, X-intercept, and Y-intercept of a line

Selecting any part of a line except the two points, on the graph may reveal additional information such as the slope and Y-intercept of a line. In some questions, this information may not be provided on purpose. If provided, a tool tip will appear with the relevant information. (Note that the slope, X-intercept, and Y-intercept do not take the units on the axes into account).

Select and drag a point from the line off of the graph.

Placing a new curve

Select and drag a curve onto the graph.

Moving a curve

Select and drag any part of the curve except the three points from one location to another.

Adjusting the endpoints of a curve

Once the curve is on the graph, select and drag one of the two endpoints on the curve from one location to another.

Adjusting the midpoint of a curve

Once the curve is on the graph, select and drag the midpoint on the curve from one location to another.

Deleting a curve

Select and drag a point from the curve off of the graph.

Placing a new triangle

Select and drag a triangle onto the graph.

Moving a triangle

Select and drag any part of the triangle except the three corner points from one location to another.

Adjusting the corner points of a triangle

Once the triangle is on the graph, select and drag any of the three corner points on the triangle from one location to another.

Finding the area and perimeter of a triangle

Place the mouse over any part of the triangle except the three corner points. Sometimes selecting a triangle on the graph will reveal additional information.(Note: The area and perimeter do not take the units on the axes into account. For triangles on the graph that you did not plot, you may or may not be able to view area information.)

Deleting a triangle

Select and drag any part of the triangle off of the graph.

Placing a new rectangle

Select and drag a rectangle onto the graph.

Moving a rectangle

Select and drag any part of the rectangle except the four corner points from one location to another.

Adjusting the edges of a rectangle

Once the rectangle is on the graph, pick an edge you'd like to move. Select and drag either of the two corner points on that edge from one location to another.

Finding the area and perimeter of a rectangle

Place the mouse over any part of the rectangle except the four corner points. If provided, a tool tip will appear with the relevant information. (Note: For rectangles on the graph that you did not plot, you may or may not be able to view area information. The area and perimeter do not take the units on the axes into account.)

Deleting a rectangle

Select and drag any part of the rectangle off of the graph.

Placing a new polygon

Select and drag a polygon onto the graph. Make sure that all corner points of the polygon are on the graph before you place it, or else the polygon will return to the palette.

Moving a polygon

Select and drag any part of the polygon except the corner points from one location to another.

Adjusting the corner points of a polygon

Once the polygon is on the graph, select and drag any of the corner points on the polygon from one location to another.

Finding the area and perimeter of a polygon

Place the mouse over any part of the polygon except the corner points. If provided, a tool tip will appear with the relevant information. (Note: For polygons on the graph that you did not plot, you may or may not be able to view area information. The area and perimeter do not take the units on the axes into account.)

Deleting a polygon

Select and drag any part of the polygon off of the graph.

Placing a new fill area

Select and drag a fill area point from the palette to the graph. To fill in regions on the graph, merely drop the fill area point on the desired region.

Adjusting the shape of a fill area

Fill areas are defined by other lines or shapes that are on the graph already. If these objects are adjustable, then adjusting the location of the objects around the fill area will adjust the area that is filled.

Removing a fill area

Select and drag the point that defines the area off the graph.

The Endpoint Mover Tool

Adjusting the position of a line with moveable endpoints

You can select any point along an endpoint mover line and drag it. Once you have moved a line far enough, it will snap into one of a few possible positions. Sometimes selecting a point on the graph will reveal additional information.

Removing endpoint movers from the graph

Endpoint movers cannot be removed from the graph.

The Shifter Tool

Adjusting the position of a shiftable line

You can select any part of a shifter line and drag it to the left or to the right. Once you have moved a line far enough, it will snap into one of a few possible positions.

Adjusting the position of the intersection point (black cross symbol) on graphs with multiple shiftable lines

Some graphs will have a black cross symbol at the intersection of two lines. Sometimes selecting the black cross symbol on the graph will reveal additional information. The location of this point will automatically adjust to the new intersection if you adjust either of the lines, but it cannot be moved independently of the lines.

Adjusting the position of a point along a line

Some shifter tools contain one line with a given point along it. To adjust the position of the point, select it and drag to the left or the right. Once you have moved it far enough, it will snap into one of a few possible positions. If you move the line the point will automatically shift along with it, but you can further adjust the location of the point along the new line, by selecting it again and dragging it to the left or right.

Removing shiftable items from the graph

Shiftable lines and points cannot be removed from the graph.

Selecting intersections for more information

The graph input tool.

Adjusting the location of the green line

Adjusting the location of the orange or blue line

Some graph input tools will contain white fields in addition to the one used to change the location of the green line. Adjusting the values in these fields will adjust the location of the blue or orange line. This will also change the values in the grey boxes (see Adjusting the values in the grey boxes).

Adjusting the values in the grey boxes

The values in the grey boxes are determined by the intersections of the lines on the graphs. These values change automatically when you change the location of the green line (see Adjusting the location of the green line) or the orange or blue line (see Adjusting the location of the orange or blue line), but they cannot be changed directly.
