Question

What does this demand curve demonstrate?

Answer 1

The demand curve demonstrates the increase or decrease in the demand for a specific product. IE: the price of a certain product and the amount that a consumer is willing to pay at that price.

Answer 2

The correct answer is:

A demand curve is a  graph that has on the y-axis the demand for that product and on the x-axis its price and it demonstrates the quantities of stores demanded at each price by consumers.

For example: if the price of the product falls, this product is preferable to look for other alternatives,  that have now become more expensive or can simply buy larger quantities of that product; thus, consumer demand for this product increases. Likewise, if price increases, demand will drop if all other things are equal.
