    Undergrad Is W a Subspace of R^3 and What is Its Geometry?

    I'm stuck on a problem which asks: Determine whether W is a subspace of R^3. If W is a subspace, then give geometric description of W. The problem is W={x:x3=2x1-x2} and x=[x1, x2, x3] I tried solving it but I'm having a hard time understanding the properties of R^n and using them. I guess I'm...
