A triangle has vertices at B(−3, 0), C(2, −1), D(−1, 2). Which transformation would produce an image with vertices B″(−2, 1), C″(3, 2), D″(0, −1)? a
(x, y) → (x, −y), (x, y) → (x + 1, y + 1)

b
(x, y) → (−x, y), (x, y) → (x + 1, y + 1)

c
(x, y) → (x, −y), (x, y) → (x + 2, y + 2)

d
(x, y) → (−x, y), (x, y) → (x + 2, y + 2)
