NettetA linear combination is any vector v cooked from these: v = a_1 v_1 + ... + a_k v_k. for some scalars a_i. There are infinitely many linear combinations, each one of them is one particular vector. A span of v_1,..,v_k is the smallest vector subspace which contains each v_i. Geometrically this is a line, plane, hyperplane etc. through the origin.
