In the following cases, find the coordinates of the foot of the perpendicular drawn from the origin.

3y + 4z – 6 = 0

Let the coordinate of the foot of P from the origin to the given plane be P(x,y,z).

x + y + z = 1


Direction ratio (1,1,1)






This is the form of


lx + my + nz = d ( d = Distance of the normal from the origin.)
