A parallelogram has coordinates A(1, 1), B(5, 4), C(7, 1), and D(3, -2). What are the coordinates of parallelogram A′B′C′D′ after a 180° rotation about the origin and a translation 5 units to the right and 1 unit down?
A=A′(-4, -2), B′(0, -5), C′(2, -2), D′(-2, 1)
b=A′(4, -2), B′(0, -5), C′(-2, -2), D′(2, 1)
c=A′(4, 2), B′(0, 5), C′(-2, 2), D′(2, -1)
d=A′(-4, 2), B′(0, 5), C′(2, 2), D′(-2, -1)
