Find an equation of a plane containing the line r=⟨0,4,4⟩+t⟨−3,−2,1⟩ which is parallel to the plane 1x−1y+1z=−5 in which the coe
ozzi

The plane you want is parallel to another plane, <em>x</em> - <em>y</em> + <em>z</em> = -5, so they share a normal vector. In this case, it's ⟨1, -1, 1⟩.

The plane must also pass through the point (0, 4, 4) since it contains <em>r</em><em>(t)</em>. Then the equation of the plane is

⟨<em>x</em>, <em>y</em> - 4, <em>z</em> - 4⟩ • ⟨1, -1, 1⟩ = 0

<em>x</em> - (<em>y</em> - 4) + (<em>z</em> - 4) = 0

<em>x</em> - <em>y</em> + <em>z</em> = 0

\begin{cases} 2x+2y=18 \\ 6x+y=39 \end{cases} \\ \\ W=\left|\begin{array}{ccc}2&2\\6&1\end{array}\right| \ W_{x}=\left|\begin{array}{ccc}18&2\\39&1\end{array}\right| \ W_{y}=\left|\begin{array}{ccc}2&18\\6&39\end{array}\right| \\ \\ W=\left|\begin{array}{ccc}2&2\\6&1\end{array}\right|=2*1-6*2=2-12=-10 \\ \\ W_{x}=\left|\begin{array}{ccc}18&2\\39&1\end{array}\right|=18*1-2*39=-60 \\ \\ W_{y}=\left|\begin{array}{ccc}2&18\\6&39\end{array}\right|=2*39-6*18=-30

x= \frac{W_{x}}{W} = \frac{-60}{-10}=6 \\ \\ y= \frac{W_{y}}{W} = \frac{-30}{-10}=3
