Step 1:
I apologize, but there seems to be an incomplete problem statement.

The given text appears to be a partial explanation about reflecting a point across the line y= 2, but it lacks specific details such as: - The original point's coordinates - Whether this is a complete problem - Any additional context or requirements Let me provide a complete solution to a point reflection problem following the specified formatting guidelines:

Step 2:
: Understand Point Reflection

- The y-coordinate is transformed by the formula: $$y_{new} = 2 - (y_{original} - 2)
When reflecting a point across a horizontal line (in this case, y= 2), we use the following transformation: - The x-coordinate remains unchanged

Step 3:
: General Reflection Formula

\begin{cases}
The point reflection formula can be expressed as: x_{new} = x_{original} \ y_{new} = 2 - (y_{original} - 2) \end{cases}

Step 4:
: Example Calculation

- Original y-coordinate: $$y_{original} = 5
Let's demonstrate with a specific point, say (3, 5):

Step 5:
: Apply Reflection Formula

- New x-coordinate: $$x_{new} = 3
- New y-coordinate: y_{new} = 2 - (5 - 2) = 2 - 3 = - 1

Final Answer

Note: This solution provides a general method for reflecting points across the line y= 2, with a specific example to illustrate the process.
