    First you have to determine the equation of the line that has a slope of 2 and goes through the point (4, 0).

    The general linear equation is y = mx+b where m is the slope so m = 2 which means y = mx+b becomes y = 2x+b

    We're given the point (4,0), so x = 4 and y = 0

    Plug these two in to get y = 2x+b 0 = 2(4)+b 0 = 8 + b Keep going to solve for b
