Argument	Description
*known_y’s*	The set of y-values you already know in the y = mx + b equation.
*known_x’s*	The optional set of x-values you might know in the y = mx + b equation.
*new_x’s*	The optional set of x-values you want y-values to be returned to.
*const*	An optional argument. It is a TRUE or FALSE value where TRUE or lack of the argument forces b to be calculated normally and FALSE sets b to 0 in the y = mx + b equation and m-values correspond with the y = mx equation.
