choose two different coordinate points. on a sheet of paper or in a graphing utility, graph the line that connects the two points.
write the equation of this line in slope intercept form. label it line a.
now create a new line in slope intercept form that is parallel to line a and that passes through the origin. label it line b.
now create a third line in slope intercept form that is perpendicular to line a and passes through the y-intercept of line a. label it line c.
