\"point-slope

\

\"\"

\

First find the slope,

\

\"\"

\

\"\"                  (Substitute \"\")

\

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

\

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

\

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 \"\".
