What is the coordinate rule for reflecting a point over the line y = -x?

Back

The coordinate rule for reflecting a point (x, y) over the line y = -x is (x, y) -> (-y, -x).

What is the coordinate rule for translating a point 2 units left and 5 units down?

Back

The coordinate rule is (x, y) -> (x-2, y-5).
