Question

A line segment has endpoints at (–4, –6) and (–6, 4). Which reflection will produce an image with endpoints at (4, –6) and (6, 4)?

Answer 1

We can see that the only change that occurs to the points after the reflection is that the x-values are negated, because -4 becomes 4 and -6 becomes 6. And the only reflection that causes only a negation in the x-values is a reflection over the x-axis.

Hope this helps
