The coordinates of the midpoint of a line are halfway between the coordinates of the points on either end of the line.To find the x-coordinate of the midpoint of AB, add the x-coordinate of A and the x-coordinate of B and divide the result by 2: (5+1)/2 = 3To find the y-coordinate of the midpoint of AB, add the y-coordinate of A and the y-coordinate of B and divide the result by 2: (8-2)/2 = 3Therefore, the coordinates of the midpoint of AB are (3,3).
