Question

The set of all possible vectors you can reach with the linear combination of two vectors is called ________________.

Answer 1

I think you can also call it a vector space.

Explanation:

Answer 2

The set of all possible vectors you can reach with the linear combination of two vectors is called the linear span of the set of two vectors.

We often write the span of a set of vectors S as span(S) and it's itself a vector space, a subspace of the vector space from which the elements of S are drawn.
