Question

I NEEEDDD HELP!

Answer 1

You research the cost of a gallon of gasoline over several years to look for a trend. The table shows your data. What is a line of best fit for the data? Based upon these prices, how much would you expect to pay in 2026?


Year 1980 1984 1988 1992 1996 2000 2004 2008 2012
Price per Gallon $1.25 $1.27 $1.05 $1.28 $1.43 $1.68 $2.11 $3.72 $3.99

(1 point)y = 0.347x + 0.856; $9.88
y = .087x – 171.26; $5.01
y = 0.134x + 1.25; $7.41
y = 0.087x + 0.587; $4.59

Answer 5

by using y = mx+b you assume that it has a linear fit. therefore, you could plug the numbers into two columns of excel and do a linear regression.
