Problem 19 of 7
Verify that the image of non-center-passing line x=-5 under dilation center (0,0), k=3 is parallel.
Using a hint is okay. It just tells the trainer to give you a little more review.
Hidden until you reveal it.
compare slopes before and after dilation.
Hidden until you reveal it.
Original line must not pass through the dilation center.
Enter your answer
Your answer is equivalent to the expected form.
Walkthrough
Full solution stays hidden until you ask for it.
1. Identify or compute the image line.
2. Find the original and image slopes.
3. Conclude parallel when slopes match or both lines are vertical.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Claiming all image lines are different without checking center-passing cases.
