  1. so much to get on board plus so much per mile
    for example if the costs were
    one mile for $10
    two miles for $15
    then
    cost = m x + b
    10 = m (1) + b
    15 = m(2) + b
    -------------- subtract
    -5 = m - 2 m = - m
    so
    m = 5
    then b = 5
    so
    cost = 5*(miles) + 5

    five to get aboard, + five per mile
    the y intercept is the cost to get on board even if you go nowhere :)
