Suppose I have the linear equation
ax+by=c   (1)
where (a,b,c)R3. Let W={a,b,c)R3:(1) is consistent}.
Is W a subspace of R3?
Apparently the answer is no, but I am unable to find a counter-example. If anything, my reasoning (below) tells me W is a subspace.
1.(0,0,0)W.
2.If (a,b,c)W, then (αa,αb,αc)W for any non-zero αR
3. If (a,b,c),(a,b,c)W, then
(a+a,b+b,c+c)W
