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 .
