Extracted text: It appears that over the past 50 years, the number of farms in the United States declined while the average size of farms increased. The following data provided by the U.S. Department of Agriculture show five-year interval data for U.S. farms. Use these data to develop the equation of a regression line to predict the average size of a farm (y) by the number of farms (x). Discuss the slope and y-intercept of the modèl. Year Number of Farms (millions) Average Size (acres) 1960 5.70 216 1965 4.69 261 1970 3.97 298 1975 3.38 343 1980 2.90 379 1985 2.51 421 1990 2.46 427 1995 2.26 444 2000 2.15 463 2005 2.06 466 2010 2.17 432 2015 2.10 445
