A 90-degree counterclockwise rotation can be achieved by swapping the x and y coordinates and negating the new x-coordinate. For a point (x, y), the new coordinates after a 90-degree counterclockwise rotation would be (-y, x). This transformation is commonly used in geometry and computer graphics to rotate objects around a fixed point.
