If u = and v = 10 then 3 5. s = {x R3 :x= au + bv for a,beR} is called the span of the set {u, v} . Acceptable notation for S is [select all that apply] O span({u, v}) O span(u, v) O span {u, v}. The span of {u, v} is a plane in R3. Using the coordinates 1, y and z, enter the Cartesian equation of the plane spanned by u and v (e.g. x+2*y+3*z=5) -9x-6y+3z=0 Recall: an effective way to write down the Cartesian equation of a plane is to use point normal form.
