This question mostly pertains to how looking at affine independence entirely in terms of linear independence between different families of vectors. I understand there are quite a few questions already online pertaining to the affine/linear independence relationship, but I'm not quite able to find something that helps my particular problem, nor am I able to make the connection on my own.
I want to try and understand how the linear independence of a family of ##n## difference vectors from any arbitrary 'origin' vector, say ##(\overrightarrow{a_i a_0}, \ldots, \overrightarrow{a_i a_j}, \ldots \overrightarrow{a_i a_n})## where ##a_i\ and\ a_j \in \mathbb{R}^{n}## and ##j \neq i## for any arbitrary 'origin' ##i \in I##, implies the linear independence of the whole family of ##(n+1)## vectors ##(\hat{a_0}, \ldots, \hat{a_n})## where ##\hat{a_j} = (1, a_j)##
I am able to understand this from the perspective of using families of points, but I am unable to visualize how I would construct this only using families of vectors. I've tried looking at the vectors as position vectors, but I think that way of thinking would not necessarily be correct.
