1. The problem statement, all variables and given/known data Determine whether the set S spans R3. If the set does not span R3, then give a geometric description of the subspace that it does span S = [ (2,0,3) , (2,0,-1) , (6,0,5) , (4,0,6) ] 2. Relevant equations 3. The attempt at a solution I know S does not span R3 because the system of equations has 3 equations but 4 variables. But how do I give a geometric description of the subspace it does span?
