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 point)
(0, 7)
(- 3, 0)
(0, 3)
(3, 0)
To rotate a point 90 degrees clockwise about the origin, we switch the x-coordinate with the y-coordinate and negate the new x-coordinate.
The original endpoint, (0, - 7), becomes (7, 0) after rotating it 90 degrees clockwise.
Therefore, the endpoint of the rotated segment is (7, 0).
So, the correct answer is (7, 0).
