Identify the transformation.

• Reflection across y axis
• Reflection across x-axis
• 180 Rotation
• Translation 2 units down

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)

Identify the transformation.

• Reflection across y-axis
• 90 Rotation counter clockwise
• Translation 5 units left, 1 unit up.
• Translation 5 units right, 1 unit down
