demonstrating the properties of rotations, if a line segment with endpoints (0, -3) and (0, -7) is rotated 90° clockwise, what is an endpoint of this rotated segment?
1. (3, 0)
2. (0, 3)
3. (-3, 0)
4. (0, 7)
To rotate a point 90° clockwise, we can switch the coordinates and change the sign of one of them.
The line segment with endpoints (0, -3) and (0, -7) is a vertical line.
If we switch the coordinates and change the sign of one of them, we get (3, 0) as a possible endpoint of the rotated segment.
Therefore, the correct answer is 1. (3, 0).
