To rotate a point \((x, y)\) 90 degrees clockwise about the origin, you can apply the transformation:
\[ (x, y) \rightarrow (y, -x) \]
For the point \((-4, -6)\):
- \(x = -4\)
- \(y = -6\)
Applying the transformation:
\[ (-4, -6) \rightarrow (-6, 4) \]
Therefore, the new point after the rotation is \((-6, 4)\).
So the correct response is:
\((-6, 4)\)
