Mrs. Morales wrote a test with 15 questions covering spelling and vocabulary. Spelling questions (x) are worth 5 point and vocabulary questions (y) are worth 10 points. The maximum number of points possible on the test is 100.
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.

Sagot :

Ok, so you are basically finding a solution of equations. 
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?
