The question asks for the coordinates of the reflection of point \( A \) across the line \( y = 2 \). Let's break this down:

1. The given point \( A \) has coordinates \( (2, -3) \).
2. The line of reflection is \( y = 2 \), which is horizontal.

### Steps to Reflect:

To reflect a point across a horizontal line, you need to calculate the vertical distance from the point to the line and then place the reflection at the same distance on the opposite side.

- The vertical distance from point \( A(2, -3) \) to the line \( y = 2 \) is:
  \[
  |2 - (-3)| = 5
  \]

- So, the reflection will be 5 units above the line \( y = 2 \). This places the new point at:
  \[
  y = 2 + 5 = 7
  \]

Thus, the coordinates of the reflection are \( (2, 7) \).

### Answer:
The reflected coordinates of point \( A \) across the line \( y = 2 \) are \( (2, 7) \).

Do you need more details on the reflection process or have any other questions?

Here are 5 related questions to explore further:
1. How would you reflect a point across a vertical line like \( x = 1 \)?
2. What are the coordinates of a point reflected over the origin?
3. How would the reflection change if the line of reflection were \( y = -2 \)?
4. Can you describe the reflection of a point across an arbitrary line \( y = mx + c \)?
5. How would you compute the reflection of multiple points across the same line?

**Tip**: For any reflection, always calculate the distance between the point and the line of reflection and then mirror that distance on the other side!
