[1,1,4] and [1,4,1] are linearly independent and they span the column space, therefore they form a valid basis for the column space. [1,2,3] and [1,1,4] are chosen in this video because they happen to be the first two columns of matrix A. The order of the column vectors can be rearranged without creating much harm here. decision tree simplilearn

Proof. Let A = [v 1 v p]. Then A is n p and the equation Ax = 0 corresponds to a system of n equations in p unknowns. If p > n, there are more variables than equations, so there must be a free variable. Hence Ax = 0 has a nontrivial solution and the columns of A are linearly dependent. decision trees and machine learning
