Question 1
Let the scale factor be k.
Then, we have the mapping

This implies that:

We equate any corresponding component find the value of the scale factor k.
6k=2


Hence the scale factor is

Question 2:
The midpoint of any two points can be calculated using the formula;

We want to find the midpoint of (-8, 5) and (2, -2).


The midpoint is:
