Reflections on the Coordinate Plane

Front

What is the reflection of a point over the y-axis?

Back

To reflect a point (x, y) over the y-axis, change the sign of the x-coordinate. The reflection is (-x, y).

Front

What is the reflection of a point over the x-axis?

Back

To reflect a point (x, y) over the x-axis, change the sign of the y-coordinate. The reflection is (x, -y).

Front

What is the reflection of R (-1, 6) over the y-axis?

Back

R'(1, 6)

Front

What is the reflection of F (3, 4) over the x-axis?

Back

F'(3, -4)

Front

What is the reflection of a point in the first quadrant over the x-axis?

Back

The reflection will be in the fourth quadrant.

Front

What is the reflection of a point in the second quadrant over the y-axis?

Back

The reflection will be in the first quadrant.

Front

What is the reflection of the point (-3, 1) across the x-axis and the y-axis?

Back

(3, -1)

Front

What type of reflection does this picture show?

Back

Reflection over the y-axis.

Front

What is the ordered pair for point A if it is located at (2, 0)?

Back

(2, 0) is the ordered pair for point A.

Front

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

Back

The x-coordinate and y-coordinate both change signs.
