Answer:
(-4, 0)
Step-by-step explanation:
The scale factor of 1/2 means each "dilated" point is 1/2 the distance from the center of dilation that the original point is. That is, the dilated point is the midpoint between the original and the dilation center.
If O is the origin of the dilation, then ...
(O + X)/2 = P . . . . . P is the dilation of point X
O +X = 2P
O = 2P -X = 2(0, 2) -(4, 4)
O = (-4, 0)
The center of dilation is (-4, 0).
_____
Another way to find the center of dilation is to realize that dilation moves points along a radial line from the center. Hence the place where those radial lines converge will be the center of dilation. See the attachment for a solution that way.
