\"point-slope\"\"

\

First find the slope,

\

\"\"

\

\"\"                      (Substitute : \"\")

\

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

\

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

\

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

\

Substitute slope and coordinates of either point in point-slope form line equation.\"\"          (Substitute:  \"\")

\

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

\

\"\"    (Multiply each side by 4)

\

\"\"           (cancel commen terms) \"\"

\

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