b.find the year in which there was approximately 815 million acres of land occupied by farms.
y=-4x+867.
(815 -867)/4 = 13. Year 1997 + 13 = 2010
..........
C.use the given equation to predict when the land occupied by farms might be 795 million acres.
y=-4x+867.
(795 -867)/4 = 18. Year 1997 + 18 = 2015
