Let W be a hyperplane in R4 spanned by the column vectors v1 , v2, and v3, where Note that these are suppose to be COLUMN vectors: v1 = [3,1, -2 , -1], v2 = [0, -1, 0 , 1], v3= [1,2 ,6, -2] Find the Cartesian (i.e., linear) equation for W. I'm not quite sure where to start or how to interpret this problem. I was thinking about first finding the span or column space?... But after that I would not know how to convert into a cartesian equation. Any guidance or tips would be appreciated. Thank you.
