A line segment has endpoints (2,−1) and (5, −4) . What are the new endpoints after rotating the segment 90° clockwise?

To rotate a point 90° clockwise, we can use the following formula:

(x', y') = (y, -x)

Applying this formula to both endpoints, we get:

For the first endpoint (2, -1):

x' = -1
y' = -(2) = -2

So, the new endpoint after rotating is (-1, -2).

For the second endpoint (5, -4):

x' = -4
y' = -(5) = -5

So, the new endpoint after rotating is (-4, -5).
