Work Step by Step

a) 7 years after purchase, valued at 225000 12 years after purchase, valued at 195000 $m=(225000-195000)/(7-12)$ $m=30000/-5$ $m=-6000$ $y=mx+b$ $y=-6000x+b$ $225000=-6000*7+b$ $225000=-42000+b$ $267000 = b$ $y=-6000x+267000$ b) $2013-1995=18$ $y=-6000x+267000$ $y=-6000*18+267000$ $y=-108000+267000$ $y=159000$
