Triangle POR has vertices P(-2,6), Q(-8, 4), and R(1, -2). It is translated according to the rule (x, y) - (x - 2, y-16). What is the y-value of pr?

Let u = {q, r, s, t, u, v, w, x, y, z} a = {q, s, u, w, y} b = {q, s, y, z} c = {v, w, x, y, z}. list the elements in the set. a ∩ (b ∪ c)a) {q, s, w, y}b) {q, y, z}c) {q, s, u, w, y, z}d) {q, r, w, y, z}
