Verified step by step guidance

1. Understand that the demand curve shows the relationship between the price of a good and the quantity demanded by consumers.
2. Recall that determinants of the demand curve are factors that cause the entire demand curve to shift, not just movements along the curve due to price changes.
3. Identify common determinants of demand, such as consumer income, tastes and preferences, prices of related goods, expectations, and the number of buyers.
4. Recognize that consumer income affects demand because as income changes, consumers' ability to purchase goods changes, shifting the demand curve.
5. Note that the cost of production, supply of the good, and number of sellers are determinants of supply, not demand, so they do not shift the demand curve.
