Answer 1

To rotate the point (9, 5) by 270 degrees clockwise, we can use the rotation formulas for a point (x, y) around the origin:

• A rotation of 90 degrees clockwise: (x, y) → (y, -x)
• A rotation of 180 degrees clockwise: (x, y) → (-x, -y)
• A rotation of 270 degrees clockwise (or 90 degrees counterclockwise): (x, y) → (-y, x)

Applying the 270 degrees clockwise rotation formula:

Starting point: (9, 5)

After rotation: \[ (-y, x) = (-5, 9) \]

Thus, the new point after rotating (9, 5) by 270 degrees clockwise is (-5, 9).

The correct response is: \[ (-5, 9) \]
