Hi bo,

b is the y intercept, where the line crosses the Y axis. It sort of places the slope on the graph paper if you will. In this picture b = 1. If the line crosses the Y axis at 0, then your b = 0 and you don't need it. http://www.mathsisfun.com/equation_of_line.html

Thank you.

Ok so using that example how do you figure out a delay needed for a given value at a given rpm? for example

2000 rpm we want a timing curve of 10 degrees BTDC. how would that work?
