MCQ
$x - 4$ is the equation of:
  • A
    $x-$axis.
  • B
    A line parallel to $x-$axis.
  • C
    $y-$axis.
  • A line parallel to $y-$axis.

Answer

Correct option: D.
A line parallel to $y-$axis.
We know that the line parallel to $y-$axis is given by $x = a$
$x - 4 = 0$
$x = 4$
So it is a line parallel to $y-$axis, at a distance of $4$ units from it, to the right.
