I know how to plot coordinates and everything but the midpoint I don't get it. So can someone please help me by explaining how to do it in a easy enough explanation please?

The midpoint between two points is simply the mean of the two points. So if point 1 is at coordinates (x1,y1) and point 2 is at (x2,y2), then the midpoint between P1 and P2 is:


P_3=(\frac {x_1 + x_2} 2 , \frac {y_1 + y_2} 2)


For example: if P1 = (3, 7) and P2 = (-5, 3) then the midpoint is at:


P_3 = (\frac {(3+-5)} 2, \frac {(7+3)} 2) \ =\ (-1,5)
