Front

When translating a figure on a coordinate plane, which coordinate is affected by movement up and down?

Back

The y-coordinate.

Front

What is a translation in the context of the coordinate plane?

Back

A translation is a transformation that moves every point of a figure the same distance in a given direction.

What is the effect of reflecting a figure over the y-axis?

Back

The x-coordinate changes sign.

Front

How do you describe a reflection in geometry?

Back

A reflection is a transformation that flips a figure over a line, creating a mirror image.

What is the line of reflection when reflecting over the x-axis?

Back

The x-axis itself.
