Answer

Graphs for zero, negative, unit, and greater than unit income elasticity of demand.

a) Zero Income Elasticity: Vertical line (demand doesn't change as income rises, e.g., salt). b) Negative Income Elasticity: Downward sloping (demand falls as income rises, inferior goods). c) Unit Income Elasticity: A straight line from the origin at a 45-degree angle (percentage change in income equals percentage change in demand). d) Income Elasticity > 1: Upward sloping but relatively flat (demand rises faster than income, luxury goods).
