Front

What is the reflection of point D(4, -5) over both axes?

Back

D'(-4, 5)

Front

Front

When you reflect a point over the x-axis, which coordinate changes to its opposite?

Back

y

Front

What axis are points reflected over if they change their x-coordinates?

Back

y-axis

Front

What is the general rule for reflecting a point (x, y) over the y-axis?

Back

The reflection is (-x, y).

Front

What is the general rule for reflecting a point (x, y) over the x-axis?

Back

The reflection is (x, -y).

Front

What happens to the coordinates of a point when it is reflected over both axes?

Back

Both coordinates change signs.

Front

If point A(3, 2) is reflected over the x-axis, what is the new point?

Back

A'(3, -2)

Front

If point E(-5, 6) is reflected over the y-axis, what is the new point?

Back
