Quiz 1.3 - Coordinate Transformations

A video visual effects animator creates an animation by translating a logo using a coordinate description. Write a rule for the translation of logo 1 to logo 2.

• (x, y) (x + 6, y – 5)

• (x, y) (x + 5, y – 6)

• (x, y) (x – 6, y + 5)

• (x, y) (x – 5, y + 6)
