    Showing Linear Subspace & Affine Subspace of Vector a in R^n

    i know that S needs to be closed under addition and numerical multiplication.. I am just not sure how to show this?!

    Showing Linear Subspace & Affine Subspace of Vector a in R^n

    Let a be a fixed nonzero vector in R^n a. Show that the set S of all vectors x such at ax=0 is a subspace of R^n. b. show that if k is a nonzero real number, then the set A of all vectors x such that ax=k is an affine subspace of R^n, but not a linear subspace.how do i even show this.. I am so...

    okay. i get it. haha... it was actually easy.. i was just a little confuse :) thanks!

    thats what I am confused about.. how would i start it off..?

    Linear equation, span, vectors, linear systems of equations

    show that S and T have the same span in R^3 by showing that the vectors in S are in the span of T and vise versa. S= {(1,0,0), (0,1,0)} T= {(1,2,0), (2,1,0)}im a little confused on how to start off on this problem.. help?!
