<h2>
The equation for a horizontal plane through the point (−4,0,−3) is z = -3</h2>
<u>Solution-</u>
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
