Yes, I'm looking for a simple way to express b in terms of the points (x1, y1) and (x2, y2) (sorry the subscripts don't work in this text). The slope m is (y2-y1)/(x2-x1), so you can write an equation for the line as (y-y1) = m(x-x1), or y = /(x2-x1)+y1, or y = mx-mx1+y1, making b = y1-mx1. I was just wondering if there is a more concice way of expressing b.
