To find the new point after rotating the point \((-6, 4)\) counterclockwise about the origin by 180 degrees, we can use the following rule: a rotation of 180 degrees transforms a point \((x, y)\) to \((-x, -y)\).
For the point \((-6, 4)\):
- Negate the x-coordinate: \(-(-6) = 6\)
- Negate the y-coordinate: \(-4\)
Thus, the new point after the rotation is \((6, -4)\).
