Question
An equation of a plane parallel to the plane x-2y + 2z - 5 = 0 and at a unit distance fromthe origin is :
Options
A.x - 2y + 2z + 5 = 0
B.x - 2y + 2z - 3 = 0
C.x - 2y + 2z + 1 = 0
D.x - 2y + 2z - 1 = 0
Solution
Equation of plane parallel to
x - 2y + 2z - 5 = 0
is x - 2y + 2z = k
or
⇒
∴ Equation of required plane is
x - 2y + 2z
x - 2y + 2z - 5 = 0
is x - 2y + 2z = k
or
⇒
∴ Equation of required plane is
x - 2y + 2z
