Verified step by step guidance

Understand that a demand curve represents the relationship between the price of a good and the quantity demanded by consumers.
Recall that in economics, the vertical axis (y-axis) typically shows the price of the good, while the horizontal axis (x-axis) shows the quantity demanded.
Recognize that the demand curve slopes downward from left to right, indicating that as price decreases, quantity demanded increases, and vice versa.
Identify that the other options given (cost of production, quantity supplied, income levels, consumer preferences) are not plotted on the demand curve axes but relate to supply or other economic concepts.
Conclude that the correct graph for a demand curve plots the price of the good on the vertical axis and the quantity demanded on the horizontal axis.
