Question 9 • A4158 Integrated Math 1b

Triangle EFG has vertices E(–3, 4), F(–5, –1), and G(1, 1). The triangle is translated so that the coordinates of the image are E’(–1, 0), F’(–3, –5), and G’(3, –3).

Answer
A
T4, –4(x, y)
B
T–4, –4(x, y)
C
T2, –4(x, y)
D
T–2, –4(x, y)

Explanation

Compare a vertex with its image: E moves from (−3, 4) to (−1, 0), which adds 2 to the x-coordinate and subtracts 4 from the y-coordinate. The same change takes F to F’ and G to G’. Therefore, the translation is T₂, −₄(x, y), choice C.
