Triangle abc has vertices at a(−3, 4), b(4, −2), c(8, 3). the triangle translates 4 units right and 3 units down. which rule represents the translation? after the translation, what are the coordinates of vertex a? a) (x, y) → ( x + 4, y + 3); (1, 7) b) (x, y) → (x + 4, y − 3); a(1, 1) c) (x, y) → (x − 4, y + 3); (−7, 1) d) (x, y) → (x − 4, y − 3); a(1, −1)
