Here's the question you clicked on:

Why do we suppose a line to be divide ONLY in ratio K:1 when solving for a line in a rectangular coordinate whose points are being divided internally or externally??
K can be anything postive or negative. While solving if it comes out to be postive then point divide internally otherwise externally. It doesnt matter with the choice of K.
dats fine but why the 1?? Why can't we go for any other number??
You can take also ratio as m:n rather than k:1, here k will be equivalent to m/n
Thanks that was exactly what i was looking for!!! :)
