Answer:

[tex](\frac{-1}{2},\frac{-1}{2})[/tex]

Step-by-step 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:

[tex](\frac{1}{4} \cdot -2,\frac{1}{4} \cdot -2)[/tex]

[tex](\frac{-2}{4},\frac{-2}{4})[/tex]

[tex](\frac{-1}{2},\frac{-1}{2})[/tex]

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