The point-slope form line equation is , where m is the slope

and  is the any point on the line.

First find the slope

           (Substitute and )

                 (Product of two same signs is positive)

                         (Add: )

                              (Divide: )

To write the line equation, we can use either of the two given points.

Consider the point .

Substitute & in point-slope form.

           (Product of two same signs is positive)

The point-slope form line equation is .
