\"point-slope\"\"

\

First find the slope,

\

\"\"

\

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

\

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

\

\"\"                                  (Add: \"\")­­

\

\"\"                                  (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 \"\".
