Step 1I'll solve this step-by-step, focusing on the rotation transformation:
Step 2: Understand the Rotation
A 270 -degree clockwise rotation is equivalent to rotating 3 / 4 of a full circle in the clockwise direction. This is the same as a - 90 -degree rotation.
Final Answer
The mapping rule for a 270 -degree clockwise rotation is (x, y) \rightarrow (-y, x), which transforms coordinates by negating the y-coordinate and setting the new y to the original x-coordinate.
