I believe its c if that is 31.5
I'm not sure how the number line looks. Do you have a picture of it?
Answer:
I got (y-7)=1/13(x+6) for point slope
and y=1/3x+13 for slope intercept form
double check me though I'm new at this
X1. Y1. X2. Y2
A= (-5,-4), B=(-3,3)
Midpoint formula = y2-y1/ x2-x1
3-(-4)/ 3-(-5) = 7/8
