The table shows the amount B (in millions of pounds) of beef produced on private farms each

Question:

The table shows the amount B (in millions of pounds) of beef produced on private farms each year from 2007 through 2014.
Year Pounds, B DATA 102.7 2007 2008 95.9 2009 90.2 2010 84.2 2011 75.0 2012 76.3 2013 70.4 2014 67.9 Jp jpayspraids Lars

(a) Use a graphing utility to create a scatter plot of the data. Let t represent the year, with t = 7 corresponding to 2007.
(b) Use the regression feature of the graphing utility to find the equation of the least squares regression line that fits the data. Then graph the model and the scatter plot you found in part (a) in the same viewing window. How closely does the model represent the data?
(c) Use the model to predict the amount of beef produced on private farms in 2020.
(d) Interpret the meaning of the slope of the linear model in the context of the problem.
