Answer 1

Answer:

C.

Step-by-step explanation:

So, if the new image coordinates are (7,9) and it is dilated from the origin there is a rule. If it is dilated from the origin you would multiply the pre-image coordinates by the scale factor so, (kx,ky) where k is the scale factor. In this case, we would divide by 2.5 so 7 divided by 2.5 is 2.8 and 9 divided by 2.5 is 3.6. The correct answer would be C. (2.8,3.6).
