Will earns $260 for working 13 hrs. multiply that by 2. 260 x 2 is 520. 13 x 2 is 26. Will earns $520 for working 26 hours. Joey earns $450 for working 36 hours. Will has a better rate of pay because he earns more than joey does, and he earns more while working less hours than joey. joey earns less money than will and he also works more hours.
5. The value of k is the same of b in the original linear equation formula (y=mx+b). The b (or k here) changes where the equation itself fits on the graph. If a +0 is replaced with a -5, then the equation is shifted down by five units. I've graphed it below for you (where f(x) is in red and g(x) is in blue). Hope this helps!
