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

Explanation

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

### Step 1: Find the midpoint of segment PQ
The midpoint S of segment PQ can be calculated using the midpoint formula:
\[ S\left(\frac{x_1 + x_2}{2}, \frac{y_1 + y_2}{2}\right) \]
where \(P(x_1, y_1) = (2, 1)\) and \(Q(x_2, y_2) = (-2, 3)\).
