My question is verifying how V5 is a subspace of R^5

Consider the subspace V5 of R° spanned by vectors { (2,0,1,1,0) & (7,–6,–1,-1,-1) & (-5,4,0,1,0) }.
Show that the subspace W5 of R spanned by vectors { (1,2,1,–3,–3) & (2,5,6,–10,–12) } is
orthogonal to V5. That is, every vector of subspace W5 is orthogonal to each vector in subspace V5.
