Determine how to translate triangle A'B'C' from triangle ABC.

• (x+2, y-5)
• (x+2, y-9)
• (x-2, y-9)
• (x-2, y+9)

Identify the transformation.

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

Describe the transformation:

(x, y) -> (x-2, y+7)

• Translation 2 units to the left & 7 units up

• Translation 2 units to the left & 7 units down

• Translation 2 units to the right & 7 units up

• Translation 2 units to the right & 7 units down
