Front

What is the line of reflection?

Back

The line of reflection is the line over which a figure is reflected, such as the x-axis or y-axis.

Front

How does reflecting a point (x, y) over the x-axis change its coordinates?

Back

The coordinates change to (x, -y).

Front

How does reflecting a point (x, y) over the y-axis change its coordinates?

Back

The coordinates change to (-x, y).

Front

What is the algebraic notation for reflecting a point over the x-axis?

Back

(x, y) → (x, -y)
