Geometry

Question Analysis:  
This question tests conceptual understanding of geometric transformations, specifically how a point behaves when reflected over the line .

Key Concept Explanation:  
Reflecting over the line transforms a point to .  
This means:
1. Coordinates swap (x becomes y and vice versa)  
2. Signs of both values change
This behavior distinguishes it from other reflections (e.g., over axes or ).

Step-by-Step Solution:  
Given a point , the reflection rule for is:
