Dilations - Writing Algebraic Representations

How do you write the algebraic notation when the scale factor is 3?

• (x, y) -> (1/3x, 1/3y)

• (x, y) -> (-3x, -3y)

• (x, y) -> (x + 3, y + 3)

• (x, y) -> (3x, 3y)

How do you write the algebraic notation when the scale factor is 1/2?

• (x, y) -> (2x, 2y)

• (x, y) -> (1/2x, 1/2y)

• (x, y) -> (-2x, -2y)

• (x, y) -> (2x, 1/2y)
