\

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)

\

\"\"              (Commutative property of Addition: \"\")

\

\"\"                     (Additive inverse property: \"\")

\

\"\"                         (Additive identity property: \"\")\"\"\"\"           (Subtract 3 from both sides)

\

\"\"                   (Additive inverse property: \"\")
