Figure 1.4 shows a visual representation of what happens in the midpoint formula. This formula starts by finding the distance between the x1 and x2 coordinates (a horizontal line) and the y1 and y2 coordinates (a vertical line).

    From here we find the middle of the vertical lines by adding the starting and ending x coordinates together and then divide this sum by two, and then repeat this step for the y coordinates to find the midpoint of the vertical lines.

    In finding the middle values of the individual lines the midpoint coordinates (x,y) have been found also.
