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.

IMPORTS LINE A graphical depiction of the relation between imports bought from the foreign sector and the domestic economy's aggregate level of income or production. This relation is most important for deriving the net exports line, which plays a minor, but growing role in the study of Keynesian economics. An imports line is characterized by vertical intercept, which indicates autonomous imports, and slope, which is the marginal propensity to import and indicates induced imports. The aggregate expenditures line used in Keynesian economics is derived by adding or stacking the net exports line, derived as the difference between the exports line and imports line, onto the consumption line, after adding investment expenditures and government purchases.
