Front

If a triangle is translated using the rule (x - 4, y + 2), what direction is it moved?

Back

4 units left and 2 units up.

Front

What is the image of a figure after translation?

Back

The image is the result of the transformation applied to the original figure.

Front

When translating a figure, which coordinate is affected by horizontal movement?

Back

The x-coordinate.

Front

What does the transformation (x, y) --> (x, y - 6) indicate?

Back

Slide down 6 units.

Front

If trapezoid ABCD is translated to A'B'C'D', what does it mean?

Back

It means that trapezoid ABCD has been moved to a new position without changing its shape or size.

Front

What is the pre-image in a translation?

Back

The pre-image is the original figure before the transformation.
