The statement that best 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 highlights that both the original segment \( XY \) and its image \( X'Y' \) have an undefined slope, indicating that they are vertical lines and thus parallel. Since the dilation does not intersect the center of dilation \((0,0)\), it confirms that the dilation does not pass through this center.
