To rotate the point (9, 5) by 270 degrees clockwise, we can follow these steps:

  1. Understand the rotation:

    • A 270-degree clockwise rotation is equivalent to a 90-degree counterclockwise rotation.
  2. Apply the rotation formula:

    • For a 90-degree counterclockwise rotation, the transformation of a point (x, y) is given by the new coordinates (−y, x).
  3. Calculating the new point:

    • Here, the point is (9, 5):
    • After applying the transformation:
      • \( x' = -y = -5 \)
      • \( y' = x = 9 \)

So the new point after a 270-degree clockwise rotation of the original point (9, 5) is (−5, 9).

Therefore, the correct response is:

(−5, 9).
