Now suppose investment spending rises to 200, will equilibrium GDP increase? Derive the answer both numerically and graphically. 2. From the following data, construct an expenditure schedule on a piece of graph paper. Then use the income-expenditure (45-degree line) diagram to determine the equilibrium level of GDP. Compare your answer with your answer to the previous question.
