Point G is rotated 90°. The coordinate of the pre-image point G was (7, –5), and its image G’ is at the coordinate (5, 7). What is the direction of the rotation?

A 90° counter-clockwise rotation about the origin changes coordinates by the rule (x, y) → (−y, x). Applying it to G = (7, −5) gives (5, 7), which matches G’. Therefore, the direction is counter-clockwise.
