\"point-slope\"\"

\

First find the slope,

\

\"\"

\

\"\"                      (Substitute \"\")

\

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

\

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

\

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

\

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

\

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

\

\"\"     (Substitute \"\")

\

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

\

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