## Answer :

x + y = 15, since there are 15 questions.

5x +10y = 100, since the maximum number of points is 100

Now what you do is change the equations to slope intercept form, which changes to y = -x+15

and y = 1/2x + 10

I assume you can graph these?

Write an equation in slope-intercept form to represent the number of questions on the test.

Write an equation in slope-intercept form to represent the total number of points on the test.

Graph the solution for both equations.

Use your graph to tell how many of each question type are on the test.
