Question

What is (4,5) reflected over the y-axis

Answer 1

Hi Sean..

Your Question: What is (4,5) reflected over the y-axis

Given: (4,5)

Find: new point when reflected over the y-axis.

Info: When you reflect over the y-axis, you can think of it like folding your paper on the y-axis. If I had a point on the right side of the y-axis, it would now be on the left side. If I had a point on the left side, it would now be on the right side.

Mathematically the transformation is your y values stay the same, but your x-values are the opposite.

y--> y, x --> -x

So for point (4,5), the y-value would stay the same and the x-value would be opposite.

(-4,5)

Hope this helps!
