Plz ! triangle abc has vertices at a(−3, 4), b(4, −2), c(8, 3). the triangle translates 2 units up and 1 unit right. which rule represents the translation? after the translation, what are the coordinates of vertex a? a) (x, y) → ( x + 1, y + 2); (−2, 6) b) (x, y) → ( x + 2, y + 1); (−1, 5) c) (x, y) → (x − 1, y + 2); (−4, 6) d) (x, y) → (x − 2, y − 1); a(−7, 3)
