Back

A translation is a transformation that moves every point of a figure the same distance in the same direction.

Front

What happens to the coordinates of a point (x, y) when it is reflected over the y-axis?

Back

The coordinates become (-x, y).

Front

What is the effect of reflecting a point over the x-axis?

Back

The y-coordinate changes sign, resulting in (x, -y).
