Answer:

A'Y' passes through the center of dilation.

Explanation:

In any dilation, the center of dilation is an invariant point: it doesn't move.

If Y is the center of dilation, then Y' and Y are the same point. Any line through Y' will go through the center, of dilation, Y.

__

Any pre-image line (not segment) containing the center of dilation will be congruent with the corresponding image line. Dilation is always along a line through the center of dilation. Lines AY and A'Y' are the same line.
