How do I determine whether or not a point lies above, below or on a 3D geometric plane.
The equation of the plane is 6x+3y+2z = 6
The equation of the plane is 6x+3y+2z = 6

The same way you know if a point lies above, below or on a line, plug in the values.
So point (1,0,0) would lie on the plane since 6=6
Point (1,1,0) lies above since 9>6
Point (0,0,0) lies below since 0<6
So point (1,0,0) would lie on the plane since 6=6
Point (1,1,0) lies above since 9>6
Point (0,0,0) lies below since 0<6
