To find the trace of the plane in the given coordinate plane.
Definition of the trace of a plane:
It is defined as the intersection of a plane with the given coordinate plane.
Let, $3x-9y+4z=5,yz.$
To find the trace of the given plane in yz plane, equate x to 0 in the equation of the given plane.
$3x-9y+4z=5$
$⇒3\left(0\right)-9y+4z=5$
$⇒0-9y+4z=5$
$⇒-9y+4z=5$
Hence, $-9y+4z=5$ is the trace of the plane in the given coordinate plane.
