This figure depicts a market (demand–D and supply–S) of a good. Consumers' disposable income increases by 20% and the equilibrium moves from point E1 to E2. Initial demand (D1) is linear and price elasticity of demand satisfies |E_D| = 1 at point E1.
The income elasticity (E_Y) of demand, given it is constant for any price level, is:
