To rotate a point \((x, y)\) 90 degrees counterclockwise around the origin, you can use the following transformation:
\[ (x, y) \rightarrow (-y, x) \]
For the point \((-4, -6)\):
- \(x = -4\)
- \(y = -6\)
Using the transformation:
\[ (-4, -6) \rightarrow (6, -4) \]
So the new point after rotating \((-4, -6)\) 90 degrees counterclockwise is \((6, -4)\).
Thus, the correct response is:
\((6, -4)\)
