Could somebody explain to me please how to figure out a geometric description of a subspace??? I understand how to check wether the set of vectors is a subset, but how t ogive them a geometric description??(adsbygoogle = window.adsbygoogle || []).push({});

lets say i have a subset in R3 {x: x3 = 2x1-x2}

why the G.D. is a plane with an equation 2x1-x2-x3 = 0??

or if I have subset {x: aTx = 0}, where a = [1;0; 0] (R3 again), the G.D is a plane yz... huh? how come? :(
