To rotate the point $(9, 5)$ by 270 degrees clockwise, you can think of this as a 90 degrees counterclockwise rotation. The formulas for rotation are:

For 90 degrees counterclockwise: $(x, y) \to (- y, x)$
For 270 degrees clockwise: $(x, y) \to (y, - x)$

Let's apply the 270 degrees clockwise (or 90 degrees counterclockwise) rotation to the point $(9, 5)$ :

Using the transformation $(x, y) \to (y, - x)$ ,

$x = 9$
$y = 5$

Now applying the transformation: $(9, 5) \to (5, - 9)$

The new point after a 270 degrees clockwise rotation is $(5, - 9)$ .

Since this point is not in your response options, it appears there may be a misunderstanding in either the provided options or the math. Please verify the options again:

Based on the standard rotation rules, if you were to additionally check:

(−9,−5)
(5,9)
(−5,−9)
(−5,9)

None of them match $(5, - 9)$ , suggesting that there might be confusion.

For clarity: A 270-degree clockwise rotation of $(9, 5)$ should yield $(5, - 9)$ . Please check your options again, or let me know if you'd like further assistance!
