In economics, a price-quantity diagram typically shows the relationship between the quantity of a good or service that consumers are willing to buy and the price at which it is offered in the market. The diagram usually has quantity on the horizontal axis and price on the vertical axis. The demand curve slopes downwards from left to right, indicating that as the price decreases, the quantity demanded increases. The supply curve, on the other hand, slopes upwards from left to right, showing that as the price increases, the quantity supplied also increases. The point where the demand and supply curves intersect is the market equilibrium, where the quantity demanded equals the quantity supplied at a particular price. **

The fairness of fuel prices is subjective and can depend on various factors such as the cost of production, taxes, and market demand. However, some may argue that the current fuel prices are not fair due to the significant increase in prices.
