To rotate a point (x, y) 270 degrees clockwise, you can use the following transformation formula:
\[ (x, y) \rightarrow (y, -x) \]
For the point (5, 8):
- Apply the transformation: \[ (5, 8) \rightarrow (8, -5) \]
So, the new point after rotating (5, 8) 270 degrees clockwise is (8, -5).
Thus, the correct response is (8, -5).
