# Math Help - Find the equation of a plane that is perpindicular to a line

1. ## 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 $N\cdot=0$.
