Question

Which ordered pair gives the coordinates of the image of D (a, -b) if D is rotated clockwise 270°?

Answer 1

(b, a)
(b, -a)
(-a, b)
(-b, -a)

Answer 2

Start with point (a, b) in Quadrant 1 as shown above.
Then rotate the point 270 deg clockwise.
You end up with the point in Quadrant 2.
Can you figure out the coordinates of the rotated point?
Remember that the coordinates can only be a, -a, b, or -b.
