Question

Z'(5,-7) is the image of Z after a reflection

in the line y = x. What are the coordinates
of Z?
(-7,-5)
(7,-5)
(7,5)
(-7,5)

Answer 1

Answer: (-7, 5) which is choice D

Reason:

Reflecting over the line y = x means that we swap the x and y coordinates.

So we'll swap the coordinates of (5, -7) to end up with (-7, 5)
