Geometry

Question Analysis:
This question involves reflecting a point across a vertical line.
The main focus is identifying how the x-coordinate changes while the y-coordinate stays the same.

Key Concept Explanation:
A vertical line like x = 4 affects the left and right position of a point
The point is flipped horizontally over the line
The x-coordinate changes, but y stays the same

Step-by-Step Solution:
Point P is at (6, 3)
The line of reflection is x = 4
P is 2 units to the right of the line (6 minus 4 = 2)
Reflect across to the left side → move 2 units to the left of x = 4
New x = 4 minus 2 = 2
Final image is at (2, 3)
