Problem 36
m = 2 is the slope
(x,y) = (-2,-7) is one of the points the line goes through
Slope Intercept Form
y = m*x + b
-7 = 2*(-2) + b
-7 = -4 + b
-7+4 = b
b = -3
So y = mx+b turns into y = 2x+(-3) or y = 2x-3
Answer: Choice D
Side note: you can use the other point as well to get to the same answer

Problem 37
Anything parallel to the x axis will be of the form y = k where k is a fixed number
The only equation that fits this description is y = 1 which is choice C
