Reflections in the Coordinate Plane ACC

Front

What is a reflection in the coordinate plane?

Back

A reflection in the coordinate plane is a transformation that flips a figure over a line, creating a mirror image.

Front

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

Back

To reflect a point (x, y) across the y-axis, change the sign of the x-coordinate to get (-x, y).

Front

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

Back

The reflection is (-3, -2).

Front

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

Back

To reflect a point (x, y) across the x-axis, change the sign of the y-coordinate to get (x, -y).

Front

What is the reflection of the point (-2, 7) across the x-axis?

Back

The reflection is (-2, -7).

Front

What is the image of the point (3, 3) when reflected across the y-axis?

Back

The image is (-3, 3).

Front

What does the reflection of a point across the x-axis look like?

Back

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

Front

If a point is reflected across the y-axis, what happens to its x-coordinate?

Back

The x-coordinate changes sign.

Front

What is the reflection of the point (2, -5) across the x-axis?

Back

The reflection is (2, 5).

Front

What is the reflection of the point (0, 4) across the y-axis?

Back

The reflection is (0, 4) because the x-coordinate is 0.
