To rotate a point \( (x, y) \) by 90 degrees counterclockwise around the origin, you can use the following transformation:
\[ (x, y) \rightarrow (-y, x) \]
For the given point \( (-7, 4) \):
\[ x = -7,\ y = 4 \]
Applying the transformation:
\[ (-7, 4) \rightarrow (-4, -7) \]
Therefore, the new point after rotating the figure 90 degrees counterclockwise is \( (-4, -7) \).
