To rotate a point \((x, y)\) by 180 degrees counterclockwise around the origin, you can use the rule:
\[ (x, y) \rightarrow (-x, -y) \]
For the point \((-4, -6)\), applying this rule gives:
\[ (-4, -6) \rightarrow (4, 6) \]
Thus, after a 180-degree counterclockwise rotation, the new point is \((4, 6)\).
The correct response is:
\((4, 6)\)
