Reflections on the Coordinate Plane

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.

Front

If point A is at (3, 4), what are the coordinates of A' after reflecting over the y-axis?

Back

(-3, 4)

Front

If point B is at (-5, -2), what are the coordinates of B' after reflecting over the x-axis?

Back

(-5, 2)

Front

What is the relationship between a pre-image and its image after reflection?

Back

They are congruent polygons.

Front

Reflect the point (2, 3) over the y-axis. What are the new coordinates?

Back

(-2, 3)

Front

Reflect the point (-4, 1) over the x-axis. What are the new coordinates?

Back

(-4, -1)

Front

What is the result of reflecting the point (0, 5) over the y-axis?

Back

(0, 5) - The point remains unchanged.

Front

If point C is at (1, -3), what are the coordinates of C' after reflecting over the x-axis?

Back

(1, 3)

Front

What is the effect of reflecting a point on the coordinate plane?

Back

It creates a mirror image of the point across the specified axis.
