I'll show you how to find the after-image point for one point, Kyinx.....you can figure the other three from this....

After-image point = [ old point - center of dilation ] *scale factor + dilation center

So.....to find the new after-image point for the point (-1, 1) we have

[ (-1, 1) - (-7, -2) ] * 2 + (-7, - 2) =

[ 6, 3] *2 + (-7, -2) =

(12, 6) + (-7, -2) =

(5, 4)

Use the same proceedure for each of the other three points on the graph above
