    Is this a calc problem? it mentions "rate of change" which is a derivative in calculus

    rate of change just means compute the slope of \[(3,20.25), (6,40.5)\]

    although, i would just say, if it's a simple problem, make it (amount earned)/(number of hours worked)

    so you get dollars per hour which is still a rate of change

    a really dumb question since unless you get paid for just showing up you might as well divide \[\frac{20.25}{3}\]

    no reason to compute a slope for sure. unless you get money for clocking in. you make $6.75 per hour

    as long as you have something/something, it's a rate of change

    20.25 ------- ; it the second data point wasnt a scalar of the first then wed have to 3 do a little more work to find the average hourly pay

    if I work for 3 hours and make 20.25; then I expect to work for 6 hours at the same pay scale and make 40.50 since I worked twice as long

    we can put in a 0 pay for 0 hours work and see if it matches up to a line or a quad :)

    (6,40.50) (3,20.25) --------- (3,20.25); slope = y/x = 20.25/3 = 6.75
