Given a quadrilateral with the vertices (-8, 9), (-8, 5), (-2, 3), and (-2, 7), construct the transformation of the image (x, y) → (x + 9, y − 5). Which is the best name for a quadrilateral with vertices at (2,2), (5,-2), (1,-5), and (-2,-1)?

My math teacher didn't go over this very well and I need some help! Math isn't my best subject and I just want to understand! Thank you!
