a) $y=58100x+2619000$ b) 2,851,400 registered nurses

a) $(0, 2619000)$ and $(10, 3200000)$ $m=(3200000-2619000)/(10-0)$ $m=581000/10$ $m=58100$ $y=mx+b$ $y=58100x+b$ $2619000=58100*0+b$ $2619000 = 0+b$ $2619000 = b$ $y=58100x+2619000$ b) $2012-2008=4$ $y=58100x+2619000$ $y=58100*4+2619000$ $y=232400+2619000$ $y=2851400$
