Best ResponseYou've already chosen the best response.1I think you misunderstood the question. a, b, and c are components of the vector, not vectors themselves. This set of vectors forms a plane through the origin, and therefore constitutes a subspace.

Best ResponseYou've already chosen the best response.1You can easily check the requirements for a subspace, also  i.e. multiply any such vector by a scalar and its components will still add to zero, and the sum of any two such vectors is another vector whose components add to zero.
