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.

CONSUMPTION LINE A graphical depiction of the relation between household sector consumption and income that forms one of the key building blocks for Keynesian economics. A consumption line is characterized by vertical intercept, which indicates autonomous consumption, and slope, which is the marginal propensity to consume and indicates induced consumption. The aggregate expenditures line used in Keynesian economics is derived by adding or stacking investment, government purchases, and net exports to the consumption line. Saving is indicated as the difference between the consumption line and the 45-degree guide line.
