Translations and Reflections

What is a translation on a coordinate plane?

• A translation on a coordinate plane is a transformation that moves only some points in a figure the same distance in the same direction.

• A translation on a coordinate plane is a transformation that moves every point in a figure the same distance in a different direction.

• A translation on a coordinate plane is a transformation that moves every point in a figure a different distance in the same direction.

• A translation on a coordinate plane is a transformation that moves every point in a figure the same distance in the same direction.

What are the coordinates of a point after a translation of (3, -2)?

• (x + 3, y - 2)

• (x - 2, y + 3)

• (x - 3, y + 2)
