If the positive z-axis points upward, an equation for a horizontal plane through the point (−4,0,−3) is

Answer-

Solution-

Let's assume n is the normal vector for the horizontal plane < 0, 0, 1 > .

The co-ordinate of the point is (-4, 0, -3)

The general equation of a plane is -

∴  The equation for a horizontal plane through the point (−4,0,−3) is z= -3
