What are the coordinates of the image of triangle abc after it is translated (x, y ) → (x + 2, y - 4)?

A.(-3,2) B(1,5) C(2,-3) < Original coordinates 

Translation being used:   (x, y ) → (x + 2, y - 4)

First: You would take your x coordinates and add two to them because that is the translation being used to solve for your x coordinate.
You would get for your x's: A (-1,_) B (3,_) C (4,_)
Next: You would take your y coordinates and subtract four from each because that is the translation being used to solve for your y coordinate. 
You would get for your y's: A (_, -2) B (_, 1) C (_, -7)
Last: You would take each one and out it together, or piece it basically.
Your answer would be: A (-1, -2) B (3, 1) C (4, -7)

HOPE THIS HELPS! ^_^
