Question Analysis:
This question involves reflecting a single point across a horizontal line.
The main focus is on understanding how a y-coordinate changes when reflected over a horizontal line.

Key Concept Explanation:
In reflection over a horizontal line, only the vertical position (the y-coordinate) changes.
The new point will be the same distance from the line, but on the opposite side.
The x-coordinate stays the same.

Step-by-Step Solution:
Original point A is at (4, 2)
The line y = 3 is above the point
Distance from A to the line is 1 unit
Reflect across the line → move 1 unit above the line
The new y-coordinate is 3 plus 1, which is 4
