A candle is 12in tall after burning for 2 hours. After 6 hours, it is 8in tall. Write a linear equation to model the relationship between height h of the candle and time t. How tall was the candle before burning/ predict how tall the candle will be after burning 10 hours. Please show steps too, thanks!
h=12, when t=2 h=8, when t=6 h=?, when t=10 m=(h2-h1)/(t2-t1) m=(8-12)/(6-2) m=(-4)/(4) m=-1 h=mt+b 12=-1(2)+b 12=-2+b 12-(-2)=b 14=b h=-1t+14 Before burning, the height was 14in After 10 hours, the height would be 4in
