Answer 1

To rotate a point (x, y) 90° clockwise, we can use the formula:

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

Using this formula for the endpoints (2, -1) and (5, -4):

For the first endpoint:
x' = -1
y' = -(2) = -2

Therefore, the new coordinates for the first endpoint are (-1, -2).

For the second endpoint:
x' = -4
y' = -(5) = -5

Therefore, the new coordinates for the second endpoint are (-4, -5).

So, the correct answer is:
(-1, -2) and (-4, -5)
