Geometry

Question Analysis:
Tests ability to determine the composition of different transformations.

Key Concept Explanation:
Composing transformations requires understanding how they interact algebraically and geometrically.

Step-by-Step Solution:
Apply to point (x, y):
Counterclockwise 90° rotation → (-y, x)
x-axis reflection → (-y, -x)
This equals reflection over y = -x
Verify with test points

Option Analysis:
A: Incorrect, it has translations that will change the x and y values.
B: Correct.
