Geometry

Question Analysis:
This question tests understanding of the 90° counterclockwise rotation rule around the origin.

Key Concept Explanation:
The rule for rotating a point (x, y) 90° counterclockwise about the origin is: (x, y) → (−y, x)

Step-by-Step Solution:
Original point: (3, 4)
Apply rotation rule: (−4, 3)

Option Analysis:
A) Incorrect, swaps coordinates without sign change.
B) Correct, follows the rotation rule.
C) Incorrect, 270° counterclockwise rotation.
D) Incorrect, reflects over the y-axis..
