Question

What is the ordered pair that represents the point (-8, 7) after a reflection over the y-axis?

A. (-8, -7)
B. (8,7)
C. (-7,8)
(7,-8) D.

Answer 1

Answer:

D (8,7)

-8 along the x-axis turns into 8 along the x-axis.
7 doesn’t change.

Think of it this way. If you’re only reflecting over the y-axis, the only number that changes is the x in the ordered pair.

If the only reflection is over the x-axis then the only number that changes is the y in the ordered pair.
