**Term consumption line intercept Definition**: The intercept of the consumption line indicates autonomous consumption, consumption that does not depend on the level of income or production. This can be thought of as the baseline level of consumption that would be undertaken if income falls to zero. Autonomous consumption is affected by the consumption expenditures determinants, which cause a change in the intercept and a shift of the consumption line. The value of the intercept of the saving line is the negative of the value of the intercept of the saving line.
