Create Graphing Questions
A graphing question provides a graphing tool in the question for students to graph points, lines, segments, rays, circles, parabolas, and inequalities on a Cartesian coordinate plane. Graphing questions are automatically scored.
 Click Questions > Create. The Question Editor opens.
 In Name, type a name for the question.
 In Mode, select Graphing.

In Question, type your question. Use the answer
placeholder string
<_>
to specify where the graphing tool should be displayed. 
In Answer, type notation that describes the objects that
you want the student to graph and the appearance of the grid. Each line in
Answer represents a separate answer and defines a new graph, so do not press
ENTER unless you wish to have
the student create multiple separate graphs.
The following table describes the notation used to specify the objects that you want the student to graph. If the student needs to graph more than one object, separate each object with a semicolon, for example:
point:(9,3);point:(6,7);point:(2,2)
Object
How to specify answer
Examples
point
Specify the point coordinates.
point: (x, y)
point: (9, 3)
line
Specify a linear equation for x and y, or specify two points on the line.
line: y = m*x + b line: y  k = m * (x  h) line: (x1,y1), (x2,y2)
line: y = 3*x  6 line: (0,6), (2,0)
ray  closed endpoint
Specify the endpoint of the ray, followed by another point on the ray.
ray: [(x1,y1), (x2,y2))
ray: [(0,0), (4,4))
ray  open endpoint
Specify the endpoint of the ray, followed by another point on the ray.
ray: ((x1,y1), (x2,y2))
ray: ((5,0), (10,12))
line segment  closed endpoints
Specify the endpoints of the line segment.
segment: [(x1,y1), (x2,y2)]
segment: [(5,0), (4,0)]
line segment  open endpoints
Specify the endpoints of the line segment.
segment: ((x1,y1), (x2,y2))
segment: ((212,45), (52,10))
line segment  closed and open endpoints
Specify the endpoints of the line segment.
segment: ((x1,y1), (x2,y2)] segment: [(x1,y1), (x2,y2))
segment: ((5,0), (52,10)] segment: [(5,0), (52,10))
circle
Specify the center coordinates and radius of the circle or specify an equation.
circle: (a, b), r circle: (xa)^2 + (yb)^2 =r^2
circle: (4, 3), 5 circle: (x4)^2+(y3)^2 = 25
parabola  vertical axis
Specify an equation for the parabola in the following form, or specify its vertex, a second point, and orientation:
parabola: y = a*x^2 + b*x + c parabola: (x1,y1), (x2,y2), V
parabola: y = (x^2)/4 + 2*x  6 parabola: (3,3), (5,5), V
parabola  horizontal axis
Specify an equation for the parabola in the following form, or specify its vertex, a second point, and orientation:
parabola: x = a*y^2 + b*y + c parabola: (x1,y1), (x2,y2), H
parabola: x = y^2  2*y parabola: (3,3), (5,5), H
dashed line or parabola
Prefix the keyword line or parabola with the keyword dashed.
dashed line: y = 3*x  6 dashed parabola: (3,3), (5,5), H
linear inequality
Specify an equation for the linear inequality.
region: y > m*x + b region: y >= m*x + b region: y < m*x + b region: y <= m*x + b region: y  k > m * (x  h) region: y  k >= m * (x  h) region: y  k < m * (x  h) region: y  k <= m * (x  h)
region: y  5 >= 3*x
circular inequality
Specify an equation for the circular inequality in the following form:
region: (xa)^2 + (yb)^2 > r^2
region: (x4)^2+(y3)^2 <= 25
parabolic inequality
Specify an equation for the parabolic inequality using the same form as for a parabola.
region: y > a*x^2 + b*x + c region: x <= a*y^2 + b*y + c
region: x > 3*y^2  5*y + 6
intersection of inequalities
Specify equations for each inequality on the same line, separated by semicolons.
region:y >= x^2  5; region:y < 2
no solution
Specify the following code for a question with no solution:
nosol
nosol
 Optional:
Type a Solution.
The solution helps your students understand the steps they need to take to determine the correct answer to the question. Your assignment settings specify when to show the solution.
 Click Test/Preview to test the appearance and behavior of the question. See Test Questions.
 Click Redisplay to show certain kinds of errors in the Display section of the Question Editor. Make any needed changes to your question.
 Optional:
Click Show Additional Information and change the
question's sharing permission or add descriptive information.
 By default, other instructors can use your question only if you provide them with the question ID, and only you can edit the question or find it in search results. To change the permission, see Share Questions With Other Instructors.
 If you make your question publicly available, you might want to provide descriptive information to help others search for it. See Add Search Metadata to Questions.

When your question displays and functions correctly, click
Save.
WebAssign assigns it a unique question ID (QID), which is displayed in parentheses after the question name.
You can use your question in an assignment and see it in your My Questions list only after it is saved.
