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 \((-4, -6)\):
- Change the sign of the x-coordinate: \(-(-4) = 4\)
- Change the sign of the y-coordinate: \(-(-6) = 6\)
So, the new point after the rotation is:
\[ (4, 6) \]
Therefore, the answer is \((4, 6)\).
