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)

                             (Subtract: )

                               (Divede: )

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

Consider the point (7, 2).

Substitute m and in point-slope form equation.

The point-slope form line equation is .
