Indifference curve
Microeconomic graph; connects points representing different quantities of 2 goods, points between which a consumer is indifferent: i.e. the consumer doesn't prefer one combination or bundle of goods over another combination on the same curve

That is, any combinations of two products indicated by the curve will provide the consumer with equal levels of utility, and the consumer has no preference for one combination or bundle of goods over a different combination on the same curve...
