Question Analysis:
Tests rotation rule for 270° CCW, equivalent to 90° CW.

Key Concept Explanation:
For a 270° CCW rotation, apply: (x, y) → (y, −x)

Step-by-Step Solution:
Given B(−6, 1)
→ Apply rule: (−6, 1) → (1, 6)

Option Analysis:
A. (6, 1) – incorrect rotation
B. ✅ (1, 6) – correct
C. (1, −6) – sign on y is wrong
D. (−1, −6) – both signs wrong

Common Mistakes:
Mixing up signs or using wrong ang...
