Reflections on the Coordinate Plane

Front

What is the reflection of point E (-3, 2) over the y-axis?

Back

E' is (3, 2).

Front

How do you reflect a point over the y-axis?

Back

Change the sign of the x-coordinate, resulting in (-x, y).

Front

If point B is at (-2, -5), what is B' when reflected over the y-axis?

Back

B' is (2, -5).

Front

How do you reflect a point over the x-axis?

Back

Change the sign of the y-coordinate, resulting in (x, -y).

Front

If point A is at (3, 4), what is A' when reflected over the x-axis?

Back

A' is (3, -4).

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

If point C is at (5, -3), what is C' when reflected over the y-axis?

Back

C' is (-5, -3).

Front

If point D is at (-1, 7), what is D' when reflected over the x-axis?

Back

D' is (-1, -7).

Front

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

Back

The x-coordinate changes sign, while the y-coordinate remains the same.
