The main thing to do here is use point-slope form to make the line, and you'll need the slope, and 2 coordinate points. The slope can be found from a slope intercept equation, where it is M. It can be found from slope formula, and it can be found as the negative reciprical to a perpindicular line and the same as a parallel line. The 2 coordinate points are usually quite obvious.
