Question

Which triangle is a translation of triangle P?

On a coordinate plane, triangle P is shifted 5 units to the right and 7 units up to form triangle C.
triangle A
triangle B
triangle C
triangle D

Answer 1

Triangle C.

A translation by 5 right and 7 up adds (5,7) to every vertex, so each point (x,y) of triangle P moves to (x+5,y+7) — that is triangle C.
