The equilibrium price and quantity of a good or service are determined by the intersection of the supply and demand curves in a market.
The supply curve shows the relationship between the price and the quantity supplied by producers, while the demand curve shows the relationship between the price and the quantity demanded by consumers.
There are two types of changes in demand that can affect the equilibrium point: an increase in demand and a decrease in demand.
An increase in demand means that consumers are willing and able to buy more of the good or service at any given price, causing the demand curve to shift to the right.
A decrease in demand means that consumers are willing and able to buy less of the good or service at any given price, causing the demand curve to shift to the left.
