Answer 1

To rotate the point (9, 5) 270 degrees clockwise, you can first note that rotating 270 degrees clockwise is equivalent to rotating 90 degrees counterclockwise.

The formula for a 90-degree counterclockwise rotation of a point (x, y) is given by:

\[
(x', y') = (-y, x)
\]

Applying this to the point (9, 5):

1. \(-y = -5\)
2. \(x = 9\)

Thus, the new coordinates after rotation are:

\[
(-5, 9)
\]

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

The correct response is:

(−5, 9)
