Please help show me how to solve this

Option C:

Solution:

Given data:

To find x - y:

Substitute y = -x.

Substitute , we get

Cancel the common factor in 2 and 4, we get

Option C is the correct answer.

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.

x is the total time in minutes for the free response

you are given number of questions as 15 - m and time per item as 8 minutes

to find x multiply the two givens together:

x = 8 * (15-m) = 8(15-m)
