Back

(-2, 3)

Front

What axis is the image reflected over when reflecting a point across the y-axis?

Back

Y-axis

Front

What is the rule for reflecting a point across the line y = 1?

Back

Subtract 2 from the y-coordinate.

Front

When translating a point up or down on a coordinate plane, which coordinate is affected?

Back

Y-coordinate

Front

What is the rule for reflecting a point across the line x = 3?

Back

Subtract 6 from the x-coordinate.

What is the reflection of the point (4, -5) over the x-axis?

Back

(4, 5)

Front

What is the reflection of the point (-1, 2) over the y-axis?

Back

(1, 2)

Front

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

Back

The y-coordinate changes sign.

Front

What is the reflection of the point (0, 0) over any axis?

Back

(0, 0)

Front

What is the rule for reflecting a point across the line y = -3?

Back

Add 6 to the y-coordinate.
