Find the slope of a line, which passes through the origin, and the mid-point of the line segment joining the points `P(0, -4) and `B(8, 0)`.

Explanation

To find the slope of the line that passes through the origin and the midpoint of the line segment joining the points P(0, -4) and B(8, 0), we can follow these steps:

### Step 1: Find the Midpoint of the Line Segment PB
The formula for finding the midpoint M of a line segment joining two points \( P(x_1, y_1) \) and \( B(x_2, y_2) \) is given by:

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