Question

If we reflect the point (-2,3) over the line y=1, what is the new point?

Answer 1

(-2,-1)

Explanation:

Since this is a reflection over the y-axis you'll keep the x-coordinate Making it (-2,?) and then since 3 is two away from y=1 on the plane you'd just count downwards two more giving you -1, so the answer is (-2,-1)
