It seems like you've uploaded an image of a coordinate plane, but I'm unable to see the specific endpoints marked on the graph.

Could you please provide the coordinates of the endpoints of the line segment you're referring to? Once I have the endpoints, I can calculate the midpoint for you!

The formula for the midpoint $M$ between two points $(x_1, y_1)$ and $(x_2, y_2)$ is:

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

Feel free to share the endpoint coordinates!
