Final Chapter 1 Review

Front

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

Back

The reflection of a point (x, y) across the y-axis is (-x, y).

Front

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

Back

The reflection of a point (x, y) across the x-axis is (x, -y).

Front

What is a 90 degrees clockwise rotation?

Back

A 90 degrees clockwise rotation of a point (x, y) results in the new coordinates (y, -x).

Front

What is a 180 degrees rotation?

Back

A 180 degrees rotation of a point (x, y) results in the new coordinates (-x, -y).

Front

What is a 270 degrees clockwise rotation?

Back

A 270 degrees clockwise rotation of a point (x, y) results in the new coordinates (-y, x).

Front

How do you translate a point (x, y) 3 units to the right and 6 units up?

Back

To translate (x, y) 3 units right and 6 units up, the new coordinates will be (x+3, y+6).

Front

What happens to the coordinates (x-4, y) when translated?

Back

The coordinates (x-4, y) will move 4 units left.

Front

What are the new coordinates of (-4, -2) after a 90 degrees clockwise rotation?

Back

The new coordinates will be (-2, 4).

Front

What is the effect of translating a point 4 units up?

Back

Translating a point (x, y) 4 units up results in the new coordinates (x, y+4).

Front

What is the effect of translating a point 4 units down?

Back

Translating a point (x, y) 4 units down results in the new coordinates (x, y-4).
