The vertices of `DeltaPQR` are `P(2, 1)`, `Q(-2, 3)`, `R(4, 5)`. Find equation of the median through the vertex `R`.

Explanation

To find the equation of the median through the vertex \( R(4, 5) \) of triangle \( PQR \) with vertices \( P(2, 1) \), \( Q(-2, 3) \), we will follow these steps:

### Step 1: Find the Midpoint of Segment \( PQ \)

The midpoint \( M \) of segment \( PQ \) can be calculated using the midpoint formula:

\[
M = \left( \frac{x_1 + x_2}{2}, \frac{y_1 + y_2}{2} \right)
