Transformation Algebraic Rules

Which rule describes the action of the coordinates when a figure is dilated by a scale factor of 2?

• (x, y)→(x+2, y+2)

• (x, y)→(2x, 2y)

• (x, y)→(x/2, y/2)

• (x, y)→(x-2, y-2)

Which rule would result in a translation of 2 units left and 3 units up?

• (x, y) → (2x, 3y)

• (x, y) → (x - 2, y + 3)

• (x, y) → (-x, -y)

• (x, y) → (x + 2, y - 3)

Is this an enlargement or a reduction?
