Answer 1

To rotate a point \((x, y)\) 90° clockwise around the origin, you can use the transformation \((x, y) \to (y, -x)\).

Let's apply this transformation to both endpoints of the line segment, which are \( (2, -1) \) and \( (5, -4) \).

1. For the point \( (2, -1) \): \[ (2, -1) \to (-1, -2) \]

2. For the point \( (5, -4) \): \[ (5, -4) \to (-4, -5) \]

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

The correct response is: \[ (-1, -2) \text{ and } (-4, -5) \] or \[ \text{(−1, −2) and (−4, −5)} \]
