To calculate the midpoint \( M \) of a line segment \( AB \) given the coordinates of points \( A(x_1, y_1) \) and \( B(x_2, y_2) \), we can use the midpoint formula:
\[ M = \left( \frac{x_1 + x_2}{2}, \frac{y_1 + y_2}{2} \right) \]
However, the specific coordinates of points \( A \) and \( B \) are not provided in your question. If you can supply the coordinates of points \( A \) and \( B \), I would be able to calculate the midpoint for you.
Please provide the coordinates of points \( A \) and \( B \).
