To find the new coordinates of the point \((-6, 4)\) when it is rotated counterclockwise 180 degrees about the origin, you can use the rule for rotation by 180 degrees. The rule states that when a point \((x, y)\) is rotated 180 degrees about the origin, the new coordinates become \((-x, -y)\).
For the point \((-6, 4)\):
- The new x-coordinate is \(-(-6) = 6\)
- The new y-coordinate is \(-4\)
Putting these together, the new point after the rotation is \((6, -4)\).
So the new point is:
\[ (6, -4) \]
