    Find the equation of a plane that is perpindicular to a line

    So I have the equation
    r(t) = (1-t, 3t, 2+2t)
    and it intersect the plane at r(1)

    I'm not sure at how I would go about solving this equation...

    Should I find out r(0) and r(1) and r(2) and from those points get two vectors and cross product the two vectors to get something perpindicular?

    NO.
    r(1)=<0,3,4> and the nornal is N=<-1,3,2>.
    So the equatuon is N\cdot<x,y-3,z-2>=0.
