Geometry

Question Analysis:
This question requires recognizing the algebraic rule for a specific rotation angle.

Key Concept Explanation:
Key rotation rules to remember:
90° CCW: (-y, x)
180°: (-x, -y)
270° CCW: (y, -x)
90° CW: Same as 270° CCW

Step-by-Step Solution:
Recall that 270° CCW = 90° CW
The 90° CW rule is (y, -x)
Therefore, 270° CCW is (y, -x)

Option Analysis:
A) 90° CCW rule - incorrect angle
B) Correct 270° CCW rule
C) Reflection over y-axis - wrong transformation
D) Reflection over x-axis - wrong transformation

Common Mistakes:
Confusing 270° CCW with 90° C...
