What are the coordinates of P'?
OA. (-7,2)
B. (-2,-7)
O, C. (-7,-2)
D. (7,-2)

Answer 1

Explanation:

The answer is (-2, -7)

Before rotated, the coordinates of P is (7,2)

Imagine if P is rotated 360° clockwise, it will come back to the initial place (7,2).

Now it is just rotated 180° clockwise, halfway of 360° clockwise. So the coordinates should be(-7,-2) after rotated 180° clockwise.
