Answer:

((-1)/(2),(-1)/(2))

Explanation:

The pre-image is E (-2,-2) and the image is found by multiplying the coordinates by 1/4 since there has been a dilation of 1/4 about the origin.

The image, E', is:

$((1)/(4) \cdot -2,(1)/(4) \cdot -2)$

((-2)/(4),(-2)/(4))

((-1)/(2),(-1)/(2))

In general if you have a dilation of k about the origin the point goes from (x,y) to (kx,ky).
