Inelastic, elastic
Elastic demand curve
Flat because quantity demand in responsive
Revenue
Price x Quantitiy
Income elasticity of demand

Ep (elasticity demand formula)
% change in quantity / % change in price
Cross price elasticity
% change in quantity of one good / % change in price of another good

Inelastic demand
A situation in which an increase or a decrease in price will not significantly affect quantity demand for the product / Ep is less than 1 Quantity is unresponsive
Negative cross price elasticity of demand
Complements - as price of one good increases, the demand for the second good decreases These 2 good are in joint demand
price elasticity of demand
Consumers responsivemess or sensitivity to changes in price
Perfectly elastic
Curve is horizontal and Ep is infinite
