The expression, M = PXX+ PYY is called a budget constraint where M = amount of money available for expenditure; PX= price of commodity X; PY= price of commodity Y; PXX= expenditure on commodity X; PYY= expenditure on commodity Y. Use M = PXX+PYY to express Y as a function of X and note that the graph of this function is called a budget line. Algebraically derive: (1) the y-intercept; (2) the x-intercept. State what determines the slope of the budget line. Graph the function for M = 120; PX= 3; PY= 5 andshow what happens to the original budget line if M decreases by 25% with PX, PY constant.

Now suppose Andrew's income is cut in half: That is, he has 50% less money to spend than he did before. On the previous graph, use the blue line (circle symbols) to plot Andrew's new budget constraint. Which of the following statements best summarizes the pattern of causality captured by the graph above? Check all that apply. The relationship between S and P is not a causal relationship. A change in E causes a shift of the budget constraint. A change in S causes a change in P. A change in P causes a change in S.

The budget constraint for a consumer who only buys apples (A) and bananas (B) is PAA + PBB = I where consumer income is I, the price of apples is PA, and the price of bananas is PB. To plot this budget constraint in a figure with apples on the horizontal axis, we should use a budget line represented by what slope-intercept equation?
