## Homework Statement

Find the equation of the plane which passes through the line [itex]\frac{x-2}{3}=\frac{y-3}{1}=\frac{z+1}{2}[/itex]

and it is normal to the plane x+4yy-3z+7=0

## Homework Equations

## The Attempt at a Solution

I find the intersection point of the plane and the line. It is M(2,3,-1). Also I got the condition (A,B,C)(3,1,2)=0

[tex]\left\{\begin{matrix}

2A+3B-C+D=0 & \\

A+4B-3C=0 &

\end{matrix}\right.[/tex]

What is the third condition ?
