You use the distance formula.
The run of a line segment is the horizontal distance between the x-coordinates of two points. To find the run, you subtract the x-coordinate of the left point from the x-coordinate of the right point. This calculation gives you the length of the base of the triangle formed by the line segment on the coordinate plane.
The length of a line segment is called the distance. To find the distance, you need to know the coordinate of its endpoints given as (x1, y1) and (x2, y2) and the distance formula.
First find the length between the midsegment point and coordinate B. The difference between 0 and -3 is 3. Thus, half the line is 3. So, to get to A, we have to go 3 in the other direction. -3 and 3 more would make Coordinate A land on (-6,2)
