Rectangle ABCD is translated according to the rule (x, y) → (x + 6, y) to rectangle A′ B′ C′ D′ and then rotated 90° counterclockwise about the origin. What are the coordinates of rectangle A″B″C″D″?
A)
A″ (1, –1), B″ (5, 1), C″ (5, –4), D″ (1, –4)
B)
A″ (1, 1), B″ (1, 5), C″ (4, 5), D″ (4, 1)
C)
A″ (–5, 1), B″ (1, –1), C″ (–1, 4), D″ (–5, 4)
D)
A″ (5, 1), B″ (1, 1), C″ (1, 4), D″ (5, 4)
