Geometry

Question Analysis:
This question involves reflecting a point over a vertical line, specifically the line .  
The main focus is on understanding how to calculate the new coordinates of a point after a geometric reflection across a vertical line.

Key Concept Explanation:
- A reflection is a transformation that flips a point across a line, creating a mirror image.
- When reflecting across a vertical line , only the x-coordinate changes.
- The new x-coordinate is found by ensuring the point and its reflection are equidistant from the line .

Step-by-Step Solution:
1. Original point:  
2. Line of reflection:  
3. Distance from point to line: units  
4. Reflection is on the opposite side:  
  Subtract the same distance from the line:
