Question

The equation of the line parallel to $Y-$axis and $3$units to the right of it, is

• A. $y=3$
• B. $y=0$
• C. $x=3$
• D. $x=0$

Answer 1

The correct option is C $x=3$

The equation of any line parallel to $Y-$axis is $x=$constant
Let the equation of required line be $x=k\cdots \left(1\right)$
Since, the line is at a distance of $3$units to the right of $Y-$axis.
$\therefore k=3$
Hence, equation of the required line is
$x=3$
