Answer:

A'(14, 2)

Step-by-step explanation:

The y-value of A is the same as the y-value of the center of dilation, so it remains unchanged.

The x-value of A is 4-(-1) = 5 units from the center of dilation, so A' will be 15 units from the center of dilation. 15 +(-1) = 14. The coordinates of A' are (14, 2).
