Answer 1

To find the new coordinates of the endpoints after a 90° clockwise rotation, we can use the transformation rules for rotation in the Cartesian plane. For a point \((x, y)\), a 90° clockwise rotation results in the coordinates \((y, -x)\).

Let's start with the first endpoint of the line segment which is \((0, -3)\):

1. Applying the rotation:
\[
(0, -3) \rightarrow (-3, 0)
\]

Now, let's do the same for the second endpoint of the line segment which is \((0, -7)\):

2. Applying the rotation:
\[
(0, -7) \rightarrow (-7, 0)
\]

Based on these calculations, the new endpoints after a 90° clockwise rotation are \((-3, 0)\) and \((-7, 0)\).

From the provided options, the endpoint \((-3, 0)\) matches one of our results.

Thus, the answer is:
\[
\text{(−3, 0)}
\]
