4. ADVANCED ANALYSIS Linear equations for the consumption and saving schedules take the general form C = a + bY and S = - a + (1 - b) Y, where C, S, and Y are consumption, saving, and national income, respectively. The constant a represents the vertical intercept, and b represents the slope of the consumption schedule. LO1, LO2 a. Use the following data to substitute numerical values for a and b in the consumption and saving equations. National Consumption Income (Y) (C) $ 0 $ 80 100 140 200 200 300 260 400 320 b. What is the economic meaning of b? Of (1 - b)
