Quizplus · Accepted Answer

Indifference curves must be downward-sloping and cannot intersect because each point on an indifference curve represents the same level of utility or satisfaction for the consumer. If two indifference curves intersected, it would imply that a single point represents two different levels of utility, which is not possible. Indifference curves need not intersect at the origin, and they can be curved rather than straight lines.
