A farmer finds there is a linear relationship between the number of bean stalks, n, she plants and the yield, y, each plant produces. When she plants 30 stalks, each plant yields 29 oz of beans. When she plants 32 stalks, each plant produces 28 oz of beans. Find a linear relationship in the form y=mn+b that gives the yield when n stalks are planted.
