Chapter 8 - Section 8.1 - Review of Equations of Lines and Writing Parallel and Perpendicular Lines - Exercise Set - Page 574: 64

a) $y=358x+31046$ b) 33,552 restaurants

a) $(0,31046)$ and $(4,32478)$ $m=(32478-31046)/(4-0)$ $m=1432/4$ $m=358$ $y=mx+b$ $31046=358*0+b$ $31046=0+b$ $31046=b$ $y=358x+31046$ b) $2012-2005=7$ $y=358x+31046$ $y=358*7+31046$ $y=2506+31046$ $y=33552$
