Answer: The dilation was an enlargement. The scale factor would be 3 for both x and y coordinates.

Step-by-step explanation: It is a dilation because the numbers seemingly get larger in figure R when compared to figure A. The scale factor is 3 for x and y because if you divide the second x coordinates by the first, and the second y coordinates by the first, you get three.

EX: x coordinates, 9/3=3. y coordinates, 12/4=3.
