The sum of twice a number, m, and 7 is equal to 15 less than the number, m. What is the value of m?

2m+7 = m-15

2m-m+7 = -15

1m = -15-7

1m = -22

m = -22

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.
