The Law of Demand and The Law of Demand and the demand curve the demand curve represents the amount represents the amount of good and services of good and services that buyers are willing to that buyers are willing to purchase at various purchase at various prices, assuming all prices, assuming all other factors are other factors are constant. As prices constant. As prices decrease of a good decrease of a good consumers buy more consumers buy more making the demand making the demand curve downward sloping.curve downward sloping.

Elastic DemandElastic Demand
Elastic Demand is the Elastic Demand is the percentage change in percentage change in one variable by the one variable by the percentage change in percentage change in another variable. By another variable. By this being done the this being done the demand for a good or demand for a good or service is more service is more elasticelastic meaning that there meaning that there ARE substitutes ARE substitutes allowing consumers to allowing consumers to pay less for the goods. pay less for the goods.

Inelastic DemandInelastic Demand
The Inelastic Demand curve is when The Inelastic Demand curve is when the quantity demanded does NOT the quantity demanded does NOT change much with a change in price. change much with a change in price. Therefore, some goods and services Therefore, some goods and services in which no substitutes are available in which no substitutes are available are generally inelastic. are generally inelastic.

If the supply of a good or other. If the supply of a good or service were to increase or decrease service were to increase or decrease it would affect the equilibrium point, it would affect the equilibrium point, which would in turn then affect the which would in turn then affect the price of the good or service.price of the good or service.
