Question

The line that is parallel to the $y-$axis, where 'K' is a constant is of the form

• A. $x=K$
• B. $y=K$
• C. both (a.) and (b.)

Answer 1

The correct option is A $x=K$

If a line is parallel to the $y-$axis then $x-$coordinate remains the same and the $y-$coordinate changes along the line.
Hence, it is of the form $x=K$

$\therefore$ Option (a.) is correct.
