To rotate the point (9, 5) 180 degrees clockwise around the origin, you can use the following transformation rule:
When you rotate a point (x, y) 180 degrees, the new coordinates will be (-x, -y).
Applying this rule to the point (9, 5):
- New x-coordinate: -9
- New y-coordinate: -5
So, the new point after a 180-degree clockwise rotation of (9, 5) is (-9, -5).
The correct response is:
(−9, −5)
