Question

The rule is applied to ΔBCD to produce ΔB"C"D". Point B" of the final image is at (–4, 1).

What are the coordinates of point B on the pre-image?

(–2, –5)
(0, –5)
(2, 3)
(5, 0)

Answer 1

Translation by (−4, 6) was applied, so undo it by adding 4 to x and subtracting 6 from y: (-4+4, 1−6) = (0, −5).

Answer: (0, −5).
