What is the pre-image in a transformation?

Back

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

How do you determine the coordinates of a translated point?

Back

To determine the coordinates of a translated point, add the translation vector to the original coordinates.

Front

If a point A has coordinates (x, y), what are the new coordinates after a translation of (3, -2)?

Back

The new coordinates will be (x + 3, y - 2).

What is the effect of translating a figure 5 units to the right and 3 units up?

Back

Each point of the figure will move 5 units to the right and 3 units up, changing their coordinates accordingly.
