Answer 3

Look at one point in the original polygon, DEFGHI.
For example, pick point D. What are the coordinates of point D?

Answer 4

-6, 6 ?

Answer 5

Correct.
Point D has coordinates (-6, 6)

Now look at point D'.
What are its coordinates?

Answer 6

After you find the coordinates of D', see what you need to add to the x-coordinate of D to get the x-coordinate of D', and to the same for the y-coordinates of D and D'.
That is the rule that the transformation used.
