To rotate a point \((x, y)\) 90 degrees counterclockwise around the origin, you can use the transformation formula:
\[ (x, y) \rightarrow (-y, x) \]
Given the point \((-7, 4)\):
- The new x-coordinate is \(-y = -4\)
- The new y-coordinate is \(x = -7\)
Thus, the new point after rotating \((-7, 4)\) by 90 degrees counterclockwise is:
\[ (-4, -7) \]
So the answer is:
\[ (-4, -7) \]
