Question

Find the equation of the line parallel to $x$ -axis and passing through $(3,-5).$

Answer 1

Let the equation of line be $y=mx+C$

Since it is parallel to $x-axis$

$\therefore m=0\therefore y=C$ and it passes through$(3,-5)$

$\therefore -5C\Rightarrow C=-5$

$\therefore$ Equation of line is $y=-5$
