\"point-slope\"\"

\

First find the slope,

\

\"\"

\

\"\"                     (Substitute  \"\")

\

\"\"                              (Subtract:  \"\")­­

\

\"\"                                (Divide: \"\")­­\"\"

\

Substitute slope and coordinates of either point in point-slope form line equation.

\

\"\"            (Substitute  \"\")

\

\"\"      (Distributive property: \"\") \ \

\

\"\"       \ \ \"\"

\

The point-slope form line equation is \"\".
