A: The common notation for the "intercept" term of an equation specified as Y = a + bX. Mathematically, the a-intercept term indicates the value of the Y variable when the value of the X variable is equal to zero. Theoretically, the a-intercept is frequently used to indicate exogenous or independent influences on the Y variable, that is, influences that are independent of the X variable. For example, if Y represents consumption and X represents national income, a measures autonomous consumption expenditures.

MARGINAL UTILITY The additional utility obtained from the consumption or use of an additional unit of a good. It is specified as the change in total utility divided by the change in quantity. Marginal utility indicates what each additional unit of a good is worth to a consumer and provides a theoretical basis for understanding market demand and the law of demand. Marginal utility generally declines with increased consumption of a good, a reflection of the law of diminishing marginal utility.
