Short Answer

In 2004 the Texas Bureau of Economic Geology published a study on the economic impact of using carbon dioxide enhanced oil recovery (EOR) technology to extract additional oil from fields that have reached the end of their conventional economic life. The table gives the approximate number of jobs for the citizens of Texas that would be created at various levels of recovery. Find the regression line. $$\begin{array} { | l | l | l | l | l | } \hline \text { Percent Recovery (\%) - } \boldsymbol { x } & 20 & 40 & 80 & 100 \\\hline \text { Jobs Created (Millions) } \boldsymbol { - } \boldsymbol { y } & 3 & 6 & 9 & 15 \\\hline\end{array}$$ ​
y = __________ x + __________
Use the regression line to estimate the number of jobs that would be created at a recovery level of 31%. Round your answers to three decimal places if necessary. $y ( 31 ) =$ ___________ million jobs
