To rotate a point \((x, y)\) 90 degrees counterclockwise around the origin, you use the transformation:
\[ (x', y') = (-y, x) \]
For the point \((-7, 4)\):
- \(x = -7\)
- \(y = 4\)
Now applying the transformation:
\[ x' = -y = -4 \] \[ y' = x = -7 \]
Therefore, the new point after rotating \((-7, 4)\) 90 degrees counterclockwise is:
\[ (-4, -7) \]
So the answer is \((-4, -7)\).
