Answer to Question 1

B

Answer to Question 2

The ZZ curve is upward sloping. The ZZ curve illustrates the level of demand at each level of income. As Y increases, households consume more causing an increase in demand. So, as Y rises, so does demand. The marginal propensity to consume will determine the size of the slope. The ZZ curve will shift when any autonomous component of demand changes. This will include changes in T, G, I and c0.
