1. The problem statement, all variables and given/known data Let L be a line in R3 passing through(-1,1,2) and is perpendicular to vectors V1 (-1,1,-1) and V2 (1,1,1). Find an equation for L in parametric form. 2. Relevant equations 3. The attempt at a solution using vector V2 (x,y,z)(1,1,1)=(1,1,1)(-1,1,2) A possible equation for L=>(x,y,z)=(-1,1,2)+t(1,1,1) I don't know if I am right.
