The most appropriate statement that proves that the dilation of ΔXYZ 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 indicates that the lines joining corresponding points in the original triangle and the dilated triangle are parallel, which means that the dilation transformation did not occur around the center of dilation, (0,0) in this case.
