Figure ABC is to be translated to Figure A'B'C' using the rule (x, y) → (x−3, y+4). Triangle ABC on the coordinate plane with th
e ordered pairs for A as 1,1, B as 2,5, and C as 3,2. Which coordinates will best represent point A'? (−2, 5) (4, −3) (−2, −3) (4, 5)

The translation P<span>(x, y) → P'(x−3, y+4)
means that every point P(x, y) is shifted :
3 units left (because of the -) and 4 units up (because of the +).
We say P was "mapped" onto P'.
Point A(1,1) is mapped to </span>A'(1-3,1+4)=A'(-2, 5).
Check the picture to see where each of the points A, B and C are mapped.
