Answer
The plane is parallel to the $z$-axis. The trace is the line $x+2y=6$.
Work Step by Step
To draw the plane, we determine its intersections with the coordinate axes. Since $z$ coordinate is not present in the equation, it does not intersects the $z$-axis. So, the plane is parallel to the $z$-axis.
To find where it intersects the $x$-axis, we set $y=0$ and obtain $x=6$.
It intersects the $y$-axis when $x=0$. So, $y=3$.
Thus, the trace is the line $x+2y=6$. The plane is shown in the figure attached.
