Answer 1

To rotate a point \((x, y)\) 90° clockwise around the origin, the new coordinates will be \((y, -x)\).

Let's find the new endpoints for the given points after rotating 90° clockwise:

1. For the point (2, -1):

   • New coordinates: \((-1, -2)\)

2. For the point (5, -4):

   • New coordinates: \((-4, -5)\)

So, after rotating the segment 90° clockwise, the new endpoints are \((-1, -2)\) and \((-4, -5)\).

Therefore, the correct answer is:

(−1, −2) and (−4, −5).
