Question 110795
a) (1,43500), (3,48500)


b) slope=(change in y)/(change in x) ... m=(48500-43500)/(3-1) ... m=2500
... units are dollars per year ($/yr)


c) slope-intercept is y=mx+b; where m is the slope and b is the y-intercept (value of y when x=0)
... y=2500x+41000
... at zero years (when Bob starts work) his salary is 41000
... his salary increases 2500 each year


d)y=2500(6)+41000 ... y=56000
