    m being slope, and you have a point so solve for b, the x-intercept being your point

    x intercept means you have the point (a,0) use point - slope \[y-0=m(x-a)\]

    if you know the x intercept you know a point. Use point slope form.

    for example if the intercept was (1,0) then 0= m(1) +b
