Which methods could you use to calculate the y-coordinate of the midpoint of a vertical line segment with endpoints at (0, 0) and (0, 15)?

One of the most convenient ways of finding or calculating for the midpoint of the line segment is to get the average of the coordinates of the points.

Average of abscissa = (0 + 0) / 2 = 0

Average of ordinate = (0 + 15) / 2 = 7.5

 Hence, the midpoint of the line segment is equal to (0, 15/2).

The value of the y-intercept is 15/2.
