To rotate a point \( (x, y) \) 180 degrees counterclockwise about the origin, you can use the following transformation:
\[ (x, y) \rightarrow (-x, -y) \]
For the point \( (-4, -6) \):
\[ (-4, -6) \rightarrow (4, 6) \]
Thus, the new point after rotating \( (-4, -6) \) by 180 degrees counterclockwise is \( (4, 6) \).
So the correct response is \( (4, 6) \).
