    by working 25 extra hours, he earned $1540 more. That's $61.60/hr

    So, his pay for x sours is

    p(x) = 61.6x-1263

    the slope is the rate of change ($ per hour), or his hourly rate.

    yea whered you get 1263 from?

  • Math-Help -

    Plug the slope of 61.6, y of 585 and an x of 30 to get the y-intercept of -1263 which is b. So your formula would be y = 61.6x - 1263 for this problem.
