Question

Translating a Figure
Triangle ABC has vertices A(4, 5), B(0, 5), and C(3, –1). The triangle is translated 3 units to the left and 1 unit up.

What are the coordinates of B' after the translation?
(1, 6)
(–3, 6)
(0, 0)
(3, 1)

Answer 1

Translate B(0, 5) left 3 and up 1: x = 0 − 3 = −3, y = 5 + 1 = 6. So B' = (−3, 6).
