Hi rachel. The coordinates above are correct, but your notation is not. (Don't use the same label for different points.)A’(-5, -3), B’(-3, -1) …
A’(-5, 3) … B’(-3, 1) …
Can you show me?Hi rachel. The coordinates above are correct, but your notation is not. (Don't use the same label for different points.)
If you treat the two steps provided for the rotation as two separate transformations, then use symbols A, A', A'' and A''' with your steps. Otherwise, treat the rotation as a single transformation and skip reporting the intermediate step above. (Use your scratch paper, instead.)
And, yes, the answer is the third choice listed in your op.

The reflection over the \(\displaystyle x-\)axis.Find the endpoints of the image of AB.
Reflect AB over the x-axis and rotate 90 degrees counterclockwise about the origin.
A” (-3, 1) B” (-5, 3)
A” (-3, -5) B” (-1, -3)
A” (3, -5) B” (1, -3)
A” (-3, 5) B” (-1, 3)
You've posted the correct answer; I had commented on a mistake in your labeling.Can you show me?
I wanted you to show me how to do the notation the proper way.You've posted the correct answer; I had commented on a mistake in your labeling.
What is it that you would like me to show you?

Hi. I explained the issue and notation in post #4. What parts are unclear?… show me how to do the notation …
I’m sorry thank you!Hi. I explained the issue and notation in post #4. What parts are unclear?
If you start with some point A, and you do two transformations, then you write them as A' and A''.
If you do three transformations, then you write them as A', A'' and A'''.
