Chapter 8 - Section 8.1 - Review of Equations of Lines and Writing Parallel and Perpendicular Lines - Exercise Set - Page 574: 62

a) $y=-1000x+13000$ b) 9,500 noodles

a) $(3,10000)$ and $(5,8000)$ $m=(10000-8000)/(3-5)$ $m=2000/-2$ $m=-1000$ $y=mx+b$ $y=-1000x+b$ $8000=-1000*5+b$ $8000=-5000+b$ $8000+5000=-5000+b+5000$ $13000=b$ $y=-1000x+13000$ b) $y=-1000x+13000$ $y=-1000*3.5+13000$ $y=-3500+13000$ $y=9500$
