(adsbygoogle = window.adsbygoogle || []).push({}); 1. {[x,y,z] | x,y,z in R, z = 3x+2}.

How do I determine if this subset is a subspace of R3? Am I wrong when I say this set contains the zero vector? If this is the case, then I have to use the addition and multiplication closure methods, right?

Thanks
