Question Analysis:
This question tests the ability to apply the 180° rotation rule.
The main focus is understanding how both coordinates change signs.

Key Concept Explanation:
180° rotation about the origin: (x, y) → (–x, –y)
It flips both x and y to their opposites.

Step-by-Step Solution:
Start with point P: (–1, –4)
Apply rule:
(–1, –4) → (1, 4)
So P′ = (1, 4)
✅ Correct Answer: A

Common Mistakes:
Only flipping one of the...
