Use the formula for average rate of change over an interval of two points:
We have two points: (-2, -1) and (0, -1). Plug the values into the formula:
The average rate of change over the interval [-2,0] is 0.

You did not attach any picture to solve this problem. We cannot calculate for the value W’X’ without the correct illustrations. However, I think I found the correct one (see attached), please attach it next time.
So the first thing we have to do is to calculate for the dilation factor. Taking point G as the reference point, we can see that the distance of point G from rectangle W’X’Y’Z’ is 1.5 while the distance from rectangle WXYZ is (1.5 + 7.5), therefore the dilation factor to use is:
dilation factor = 1.5 / (1.5 + 7.5) = 1.5 / 9 = 1/6
Since WX has an initial measure of 3 units, therefore the measure of W’X’ is:
W’X’ = 3 units * (1/6) = 0.5 units
