The statement that proves that the dilation of \( \Delta XYZ \) does not pass through the center of dilation is:
"XY¯¯¯¯¯¯¯¯ and X′Y′¯¯¯¯¯¯¯¯ both have an undefined slope with a center of dilation at (0,0). This proves that the lines are parallel and that the dilation does not pass through the center of dilation."
This statement suggests that since the lines \( XY \) and \( X'Y' \) are parallel and do not intersect at the center of dilation, it confirms that the dilation does not pass through that point.
