To find the new point after rotating the point \((-6, 4)\) counterclockwise about the origin by 180 degrees, we can use the transformation for a 180-degree rotation.
The formula for rotating a point \((x, y)\) by 180 degrees around the origin is given by:
\[ (x', y') = (-x, -y) \]
Applying this to the point \((-6, 4)\):
\[ x' = -(-6) = 6 \] \[ y' = -4 = -4 \]
So the new point after the rotation is:
\[ (6, -4) \]
Thus, the new point is \((6, -4)\).
