To find the midpoint of a segment where the endpoints are known, you just add the x values of the endpoints and divide by 2 and add the y values of the endpoints and divide by 2. That will be the (x, y) coordinates of the midpoint.
So, with point A at (6, -5) ant point B at (4, 3) the x value of the midpoint is (6 + 4)/2 = 5 and the y value of the midpoint is (-5 + 3)/2 = -1 making the midpoint at (5, -1)
