1.A candle is 17 in. tall after burning for 3 hours. After 5 hours, it is 15 in. tall. Write a linear equation to model the relationship between height h of the candle and time t. Predict how tall the candle will be after burning 8 hours.
2.You research the average cost of a tank of gasoline for a certain type of car for several recent years to look for trends. The table shows your data. What is the equation for a line of best fit? How much would you expect to pay for a tank of gas in the year 2024? Table:
1996 2000 2002 2004 2006 2008
26.10 28.50 30.30 29.70 32.50 37.70

Well every 2 hours it burns 2 inches. So its burning an inch an hour. The linear equation for that would be (Y = X + 20) Where Y is the time gone by, and X is the height of the candle. To find how tall it is after eight hours, substitute 8 in for 8. Your answer in 12 inches tall. And for the second part, I have forgotten how to do line or regression sorry.

I'm really very terrible at figuring out line of best fits and equations to figure out what the next point would be :/ one of the things I simply never understand nomatter how much I research it.
