Question

Triangle ABC is going to be reflected over the line y = X.

If A is located at (1,-7), where will A' be located?

Answer 1

(-7, 1)

Explanation:

Coordinate rules :]

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)
