Geometry

Question Analysis：
This is a basic coordinate reflection question focusing on reflecting a single point over y = x.

Key Concept Explanation:
To reflect over y = x, apply the rule (x, y) → (y, x).
Signs are not changed unless part of the original point.

Step-by-Step Solution：
Original point: (–7, –3)
Swap x and y: (–3, –7)

Option Analysis：
A. Incorrect — both signs flipped
B. ✅ Correct — values swapped, signs unchanged
C. Incorrect — swapped and flipped
D. Original point,...
