Transformations: Review

Triangle RST has vertices R(–1, 1), S(3, 1), and T(3, –4). What are the coordinates of the image of RST after a translation 4 units to the left and 2 units down?

• R'(–5, 1), S'(–1, 1), and T'(–1, –4)

• R'(–5, –1), S'(3, –1), and T'(–1, –4)

• R'(–1, –1), S'(3, –1), and T'(3, –6)

• R'(–5, –1), S'(–1, –1), and T'(–1, –6)
