MCQ
The equation of a plane parallel to X -axis is
  • A
    $a x+b y+c z+d=0$
  • B
    $a x+b y+d=0$
  • ✓
    $b y+c z+d=0$
  • D
    $a x+c z+d=0$
✓

Answer

Correct option: C.
$b y+c z+d=0$
(C)
Since, the plane is parallel to X -axis,
∴ the d.r.s. of the normal to the plane are $0, b, c$
$\therefore \quad$ The equation of required plane is $b y+ cz + d =0$
