EXPLANATION
The given line in the graph has equation

This line is a horizontal line.
All horizontal line has a slope of 0.
Let the equation of the line that is parallel to this line be

The slope of this line must also be zero.
We substitute the slope, m=0 and the point (3,-1) into this equation to get:


Hence the required equation is

A. For a I got 9 as the change. Sorry I did my best. B. 153.334 as the rate of change
