The law of demand states that, if all other factors remain equal, the higher the

price of a good, the less people will demand that good. In other words, the higher the price, the lower the quantity demanded. The amount of a good that buyers purchase at a higher price is less because as the price of a good goes up, so

does the opportunity cost of buying that good. As a result, people will naturally

avoid buying a product that will force them to forgo the consumption of something else they value more. The chart below shows that the curve is a downward slope.


A, B and C are points on the demand curve. Each point on the curve reflects a direct correlation between quantity demanded (Q) and price (P). So, at point A, the quantity demanded will be Q1 and the price will be P1, and so on. The demand relationship curve illustrates the negative relationship between price and quantity demanded. The higher the price of a good the lower the quantity demanded (A), and the lower the price, the more the good will be in demand (C).
