The following graph shows the aggregate demand curve (AD1 ) for this economy before the change in government spending. On the following graph, use the green line (triangle symbol) to plot the new aggregate demand curve (AD2) after the multiplier effect takes place. For simplicity, assume that there is no "crowding out." Hint: Be sure that the new aggregate demand curve (AD2) is parallel to the initial aggregate demand curve (AD1 ). You can see the slope of ADI by selecting it on the graph. PRICE LEVEL 140 135 130 125 120 115 110 105 100 AD 6 2 3 REAL GDP (Trillions of dollars) AD2

Question
Not sure how to figure out the slope and y-intercept
Consider a hypothetical closed economy in which households spend $0.70 of each additional dollar
they earn and save the remaining $0.30.
The marginal propensity to consume (MPC) for this economy is 0.7
this economy is 3.3333 Y
Suppose the government in this economy decides to decrease government purchases by $300
billion. The decrease in government purchases will lead to a decrease in income, generating an
This decreases income yet again,
initial change in consumption equal to -$210 billion
causing a second change in consumption equal to -$147 billion
resulting from the initial change in government spending is -$1 trillion
.The total change in demand
