A triangle has vertices at B(-3,0), C(2, -1), D(-1,2). Which transformation would produce an image with vertices B"(1, -2), C"(0,3), D"(3, 0)?
O(x, y) (x + 1, y + 1), (x, y) (y, x)
O(x, y) = (x + 1, y + 1), (X, Y) + (-x, y),
(x, y) → (X, -y), (x, y) → (X + 2, Y + 2)
(x, y) → (-x, y), (x, y) + (x + 2, Y + 2)
