although this subspace only contains a single vector, (0, 0, 0), it satisfies all criteria for a subspace. Multiplying by any constant will return something within the subspace (0, 0, 0) and adding with other vectors in the subspace will also return something in the subspace (0, 0, 0) + (0, 0, 0) =
