JASS:
library LineSlopeIntercept
    //returns the slope given vector [(x1, y1), (x2, y2)]
    function GetVectorSlope takes real x1, real y1, real x2, real y2 returns real
        return (y2-y1)/(x2-x1)
    endfunction
    
    //returns y intercept given point (x,y) and slope m
    function GetLineYIntercept takes real x, real y, real m returns real
        return y-m*x
    endfunction
