We will have the following:
*First: We determine the translation rule:
We have that the point went from (3, -4) to (0, -5), thus the translation rule would be:
Second: We apply the translation rule to the other point to determine it's image, that is:
So, the image of the second point is (5, 6).
8 because inverse operations indicate that 4x2=8
