Step 2
: Understanding Reflection

A reflection across a vertical line (in this case, $$x = -2$$) means every point is transformed by:
- Keeping the vertical (y) coordinate exactly the same - Changing the horizontal (x) coordinate by an equal distance from the line of reflection

Final Answer

x = - 2 while maintaining its vertical position.
