Determine the relative position of three planes:
\begin{align*}
\alpha\colon\ &2x+y+9z-18=0, \\
\beta\colon\ &x+3y+2z+16=0, \\
\gamma\colon\ &x+2y+3z+6=0.
\end{align*}
Planes $\alpha$, $\beta$ and $\gamma$ intersect in a straight line.
Each of the two planes are intersecting and the lines of intersection are three different lines parallel to each other.
All three planes intersect at just one point.
