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 sins is positive)

                                 (Add: )

                                 (Multiply: )

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

Consider the point .

Substitute m & in point-slope form.

                   (Product of two same sins is positive)

The point-slope form line equation is .
