\

The line equation of standard form is $\"\"$ , where A > 0 and A, B,C are integers.

\

Substitute slope m = 3 and $\"\"$ in point–slope form line equation.

\

$\"\"$ (Product of two same signs is positive)

\

$\"\"$ (Apply distributive law: a (b + c) = ab + ac) $\"\"$

\

Rewrite the above equation in standard form,

\

$\"\"$ (Subtract ‘y’ from both sides)
