Fracking has allowed energy producers to extract oil and natural gas from previously unrecoverable deposits. One such deposit is the Marcellus Shale formation. Large scale fracking begun in 2008. The number of fracking- related jobs changed from 9,900 in 2008 to 30,000 in 2013. a. The linear regression model most closely fitting this data (where g represents number of fracking- related jobs and t represents years since 2008 is: a-g=4020t+9900 b. g= 4020t+2008 c. g= 20100t +2008 d. g=20100t +9900. B. Use the model to predict number of fracking related jobs in western Pa. in 2018(DO NOT ROUND ANSWER) SHOW WORK C. Fill in the blanks to interpret the slope of the equation: The rate of change if tracking-related jobs in western Pa. with respect to time is___________per________(_((include units of measurement
