Write the equation of the plane parallel to XOY- plane and passing through the point (2, −3, 5).
उत्तर
The equation of the plane parallel to the plane XOY is z=b ... (1), where b is a constant.
It is given that this plane passes through (2,-3, 5). So,
5=b
Substituting this value in (1), we get
z=5, which is the required equation of the plane.
