<h3>The linear equation of the graph </h3>
Start by calculating the slope of the line of best fit using:
From the line of best fit, we have:
The regression equation is then represented as:
So, we have:
Express as decimals
In 2001, the value of x is 1
So, we have:
In 2013, the value of x is 13.
So, we have:
So, the difference (d) between the prices is:
Hence, the difference between the gas prices in 2013 and 2001 is 3.00
