Mrs. Morales wrote a test with 16 questions covering spelling and vocabulary. Spelling questions (x) are worth 5 points and vocabulary questions (y) are worth 10 points. The maximum number of points possible
on the test is 100.
Part 2 out of 4
Write an equation in slope-intercept form to represent the total number of points on the test.

Step-by-step explanation:

X+Y = 15

x+y-x = -x+15

5(x)+10(y)=100

5x+10y=100

5x+10y-5x=-5x+100

10y= -5x+100

y=5/10x + 100/10

y= -1/2x+10
