Write the equation of the plane parallel to XOY - plane and passing through the point (2, –3, 5)
Equation of XOY plane is z=0.
Since the required plane should pass through the point (2, - 3, 5).
We know, the vector equation of a plane perpendicular to a given direction
and passing through a given point(
) is given by,
![]()
i.e. ![]()
![]()
⟹ (z - 5)=0

⟹ z=5
here
is given by
as it is perpendicular to XOY plane, and here
![]()
Hence, the desired equation for the plane is z=5.
