Answering Graphing Questions

The WebAssign graphing tool lets you graph one or more mathematical elements directly on a set of coordinate axes. Your graph is scored automatically by WebAssign when you submit the assignment for grading.

If needed, high school students can continue to use an older version of the graphing tool that requires Flash® through Spring 2020.

Note If prompted, do not select Prevent this page from creating additional dialogs. The graphing tool requires dialog boxes to complete actions like Clear All and No Solution. If you already selected this option, see Graphing Tool is Not Responding.

The WebAssign graphing tool supports points, rays, segments, lines, circles, and parabolas. Inequalities can also be indicated by filling one or more areas.

When you work on a graphing question, the WebAssign graphing tool displays below the question.

The middle of the graphing tool is the drawing area. It contains labeled coordinate axes, which may have different axis scales and extents depending on the nature of the question you are working on.

The left side of the graphing tool contains tools for drawing and selecting objects, as well as the No Solution button. If there is no possible solution to a graphing question, click No Solution.

The right side of the graphing tool contains tools for deleting objects and filling regions of the graph.

Click open Graph Layers to open the Graph Layers tool. You can view and edit the properties of graphed objects in Graph Layers.

Depending on the question, the graphing tool might display both x and y axes, or only the x axis. If only the x axis is displayed, you can specify only x coordinates; the y coordinate will always be 0. The maximum and minimum allowed values on the graph in the graphing tool are also dependent on the question.

  1. Graph an object.
    To do thisDo this
    Graph a point
    1. Click add a point.
    2. Click a location in the graph.
    Graph a line, ray, or line segment
    1. Click add a line to expand the line tools, and click the object you want to graph.
    2. Click the location of the first point.
    3. Click the location of a second point.
    Graph a circle
    1. Click add a circle.
    2. Click the location of the center of the circle.
    3. Click the location of a point on the circle.
    Graph a parabola
    1. Click add a parabola to expand the parabola tools, and click the object you want to graph.
    2. Click the location of the vertex of the parabola.
    3. Click the location of another point on the parabola.
  2. Edit the graph.
    To do thisDo this
    Move an object
    1. Click select an object.
    2. Click and drag an object to a new location.
      You can also move an object by editing its points in Graph Layers.
      Note Parabolas must be moved by editing points in Graph Layers.
    Reshape an object
    1. Click select an object.
    2. Click an object to select it.
    3. Click and drag a point on an object to a new location.

      You can also reshape an object by editing its points in Graph Layers.

    Set an open/closed endpoint for a ray or line segment Click an endpoint on the graph to toggle between open and closed.
    Set a dashed line style to specify inequality
    1. Click select an object.
    2. Click an object.
    3. In Graph Layers, click Dash.
    Delete an object
    1. Click select an object.
    2. Click an object.
    3. Click Delete.
    Delete all objects
    1. Click Clear All.

      A message displays to confirm that you want to delete all objects.

    2. Confirm that you want to clear the graph.
    Fill a region of the graph
    Note Clicking any button in the graphing tool after you add fills will remove them, so be sure to fill regions last.
    1. Graph objects to create boundaries for the inequality.
    2. Click Fill.
    3. Click a location in the region to fill.
  3. Click Submit.

    A correct or incorrect icon displays in the lower right corner of the graphing tool.
