Consider the triangle defined by P = (1, 3), Q = (2, 5), and R = (6, 5). The transformation defined by T(x, y) = (x + 2, y – 1) is mathematical notation for translating a point two units to the right and one unit down. The point P(1, 3) becomes T(1, 3) = (1 + 2, 3 – 1) = P′(3, 2). Find Q′ and R′. Graph both the original triangle and its image.
