consumer equilibrium question economics

1.  Assume consumer equilibrium (budget curve and indifference curves).  Draw 3 separate scenarios: (1) the price of good x decreases; (2) the price of good y increases; and (3) the budget (income increases).  In each scenario, explain the effect on the graphed lines, on the relative price between the goods, and the final consumption of good x and good y (increases or decrease).
