Question

If the triangle on the grid below is translated three units left and nine units down, what are the coordinates of C prime?

On a coordinate plane, triangle A B C has points (negative 1, 0), (negative 5, 2), (negative 1, 2).
(–4, –7)
(–4, 2)
(2, –7)
(2, 11)

Answer 1

C = (−1, 2). Translate 3 left: x = −1 − 3 = −4. Translate 9 down: y = 2 − 9 = −7.

So C′ = (−4, −7).
