Geometry

Question Analysis：
This question tests whether the student can recognize points on the line y = x, where reflection does not change position.

Key Concept Explanation:
Points on the line y = x have equal x- and y-coordinates: x = y.
These points reflect onto themselves.

Step-by-Step Solution：
A. (4, 4): x = y ✅
B. (–2, 2): x ≠ y ❌
C. (0, 0): x = y ✅
D. (5, –5): x ≠ y ❌
E. (–3, –3): x = y ✅

Common Mistakes：
Confusing y = x...
