9) With the help of scientists, farmers in Cameroon have been able to produce more and more grain per hectare each year. Here are the crop yields for several years: The crop yield can be described by the equation y = 30.6x - 59500 where x is the year and y is the grain yield in kilograms per hectare (kg/ha). Year Yield (kg/hectare) 2400- 1963 630 2000 1967 706 1600 1980 740 1993 1,150 1200 2000 1,630 800 2006 2,060 1960 1980 2000 2020 Year a) What does the y-intercept of this function represent? b) According to the model, what was the crop yield in 1974? Round your answer to the nearest whole number. Yield (kg/hectare)
