The combination of two goods which a consumer derives equal satisfaction from is plotted on a graph known as an indifference curve. This graph represents all the different combinations of two goods that provide the consumer with the same level of utility or satisfaction.

For instance, if a consumer is equally happy with either 3 bananas and 2 apples or 2 bananas and 3 apples, both points will lie on the same indifference curve.

The reason it's called an indifference curve is because the consumer is indifferent between any two points on this curve, meaning they have no preference for one combination over the other since both provide the same level of satisfaction.

Unlike a demand curve which shows the quantity of a good that consumers are willing and able to purchase at various prices, the indifference curve focuses solely on the level of satisfaction from different combinations of goods, without considering their prices directly. It is an essential concept in the study of consumer behavior and helps understand how consumers make choices between different goods.
