Using section formula, show that the points `A(2,-3,4),\ B(-1,2,1)\ a n d\ C(0,1/3,2)\ ` are collinear.

Text Solution

Verified by Experts

Let, C divides AB in the ratio `λ:1` Then, the coordinates of C are
`((-lambda+2)/(lambda+1) , (2lambda+3)/(lambda+1), (-lambda+4)/(lambda+1))`
But the coordinates of C are `(0,1/3,2)`
