Problem 125 of 7
Complete the proof of dilation line behavior: Line m contains the center of dilation C. Point P is on m and P' is its image.
Using a hint is okay. It just tells the trainer to give you a little more review.

Full solution stays hidden until you ask for it.
1. Identify whether line passes through center.
2. Use ray reasoning for center-passing lines or slope reasoning otherwise.
3. State same-line or parallel-line conclusion.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Unsupported statements that dilation preserves all lines unchanged.
