1. span of 2 vectors(v,w) : is the set of all their linear combinations : av + bw ex: Appartment [price, surface] is a kind of vector.

=> Think about them as point.

2. the basis of a vector space is a set of linearly independant vectors that span the full space. "La base d'un espace vectoriel est un ensemble de vecteurs linéairement indépendants qui couvrent tout l'espace".
