how do you find the midpoint on of a line on a graph with an equation?
Assuming that you know the x and y coordinates of two points on the line ....the midpoint is given by :
Add the x coordinates and divide by 2 = x midpoint coordinate
Add the y coordinates and divide by 2 = y midpoint coordinate
Example
(5, 6) and ( 7, 8)
Midpoint = [ ( 5 + 7) / 2 , (6 + 8) / 2 ] = [ 12/ 2, 14/2 ] = [ 6, 7 ]
