## Homework Statement

Find the equation of the plane which passes through M(2,3,1) and the line

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

2x-y+3z-1=0 & \\

5x+4y-z-7=0 &

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

## Homework Equations

[tex]\frac{x-x_1}{\begin{vmatrix}

B_1 & C_1\\

C_1 & C_2

\end{vmatrix}}=\frac{y-y_1}{\begin{vmatrix}

C_1 & A_1\\

C_2 & A_2

\end{vmatrix}}=\frac{z-z_1}{\begin{vmatrix}

A_1 & B_1\\

A_2 & B_2

\end{vmatrix}}[/tex]

## The Attempt at a Solution

first I find the equation of the line:

[tex]\frac{x}{-1}=\frac{y+7}{-5}=\frac{z+3}{-3}[/tex]

What should I do next?
