Question

Write the equation of line parallel to $x-$axis and distance $6$ unit from below the $x-$axis.

Answer 1

Find the equation of the required line:

The equation of line parallel to $x-$axis is of the form $y=c$ where $c$ is a constant.

As the line lies at distance $6$ unit from below the $x-$axis, $y=-6$.

Hence, the equation of line parallel to $x-$axis and distance $6$ unit from below the $x-$axis is $y=-6$.
