To rotate a point \((x, y)\) 180° counterclockwise around the origin, you can use the transformation:
\[ (x, y) \rightarrow (-x, -y) \]
Given the point \((-4, 6)\), we will apply this transformation:
\[ (-4, 6) \rightarrow (4, -6) \]
So the resulting point after rotating \((-4, 6)\) 180° counterclockwise is \((4, -6)\).
Thus, the answer is \(4. \ (4, -6)\).
