Say the coordinates at each end are (x1,y1) and (x2,y2)

The x coordinate of the midpoint will be (x1+x2)/2

The y coordinate of the midpoint will be (y1+y2)/2

To find the midpoint of a line segment, find the average of the x co-ordinates of each end and the average of the y co-ordinates of each end.

Example: Point A (3, 7) Point B (5, 10)

The x co-ordinate of the midpoint will be (3 + 5) divided by 2 = 4

The y co-ordinate of the midpoint will be (7 + 10) divided by 2 = 8.5

So the co-ordinates of the midpoint are (4, 8.5).
