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
