as we know that for the co ordinates of a point whic divides externally in ratio m:n
(x,y)=(mx2-nx1)/m-n,  (my2-my1)/m-n
let us take x1=1,y1=2
x2=3 , y2=4
m=1, n=1
by the above formula
(1*3-1*1)/1-1 (1*4-1*2)/1-1
we will get x,y as infinity so we can say there is no  point which divides line in ratio 1:1 externally for any line joining two points
