To rotate a point \( (x, y) \) by 180 degrees clockwise, you can apply the transformation \( (x, y) \rightarrow (-x, -y) \).
For the point \( (5, 8) \): \[ (-5, -8) \]
So the new point after rotating \( (5, 8) \) 180 degrees clockwise is \( (-5, -8) \).
The correct response is: \[ \text{(−5, −8)} \]
