Answer:
Step-by-step explanation:
First, we will find the midpoint for the x - coordinate first.
Midpoint (x) = 
Now we will find the midpoint for the y - coordinate.
Midpoint (y) = 
Therefore from these 2 values we know that the midpoint of this 2 points is (-3.5,-0.5)
Rate of change is slope
So change in y/change in x
150/3=50
