In the linear consumption function

The (estimated) marginal propensity to consume (MPC) out of income is simply the slope, , while the average propensity to consume (APC) is

Using observations for 100 families on annul income and consumption (both measured in dollars), the following equation is obtained:

(i) Interpret the intercept in this equation, and comment on its sign and magnitude.
(ii) What is the predicted consumption when family income is $30,000?
(iii) With inc on the x-axis, draw a graph of the estimated MPC and APC.

cons -P +Binc cons/inc-B/inc + cons =-124.84 + 0.853 inc n = 100, R2 = 0.692.
