Question

Triangle ABC is going to be reflected over the y-axis.

If A is located at (4,3), where will A' be located?

Answer 1

(-4, 3)

Explanation:

There are coordinate rules for reflection that really help me with these:

Reflection over x-axis -- (x, y) -> (x, -y)

Reflection over y-axis -- (x, y) -> (-x, y)

Reflection over y = x -- (x, y) -> (y, x)

Reflection over y = -x -- (x, y) -> (-y, -x)

Hope this helps :]
