Geometry

Question Analysis:
This question is about a series of geometric transformations.
The main goal is to determine the original point by reversing a sequence of transformations that includes two reflections across the line and a translation.

Key Concept Explanation:
  - Reflection across the line : When a point is reflected across the line , its coordinates are swapped, i.e., .
  - Translation by a vector : When a point is translated by the vector , the new point is .
To reverse a translation by , we use the vector .

Step - by - Step Solution:
  - Reverse the last reflection across :
    - Given
