an increase in price level would lead to a fall in AE, vice versa. So by plotting those points out, you can derive an AD curve
How to Derive Demand curve mathematically. In Simple Language With simple Examples.
An increase or decrease in consumption, investment, government expenditure or net exports
Aggregate demand curve.
The aggregate demand curve shifts to the right
Movements along the aggregate demand curve are caused by changes in price level - real wealth effect, interest rate effect and open economy effect. If some non-price level determinant causes total spending to increase/decrease then the curve will shift to the right/left - consumption, investment, government expenditure, net exports.

aggregate demand curve is the total sum of all the individual demand curves while individual demand curve is the demand made by the single individual.
Movements along the aggregate demand curve are caused by changes in price level - real wealth effect, interest rate effect and open economy effect. If some non-price level determinant causes total spending to increase/decrease then the curve will shift to the right/left - consumption, investment, government expenditure, net exports.
Total income depends on total employment which depends on effective demand which in turn depends on consumption expenditure and investment expenditure. Consumption depends on income and propensity to consume. Investment depends upon the marginal efficiency of capital and the rate of interest. J. M. Keynes made it clear that the level of employment depends on aggregate demand and aggregate supply. The equilibrium level of income or output depends on the relationship between the aggregate demand curve and aggregate supply curve. As Keynes was interested in the immediate problems of the short run, he ignored the aggregate supply function and focused on aggregate demand. And he attributed unemployment to deficiency in aggregate demand.
The aggregate expenditure curve is upward sloping because it represents the relationship between total spending in an economy and the level of real GDP. As GDP increases, consumption, investment, and other components of expenditure typically rise due to higher incomes, leading to increased overall spending. This positive correlation shows that as economic output grows, so does the aggregate demand for goods and services, resulting in the upward slope of the curve.
The aggregate demand curve shows the relationship between the quantity of real GDP demanded and the price level when other influences on expenditure plans remain the same. When there is a movement along the aggregate demand curve, the price level changes and other factors such as expectations, fiscal and monetary policy, and the world economy remain the same
The aggregate demand curve show what consumers are willing to buy at a given price level, whereas the aggregate supply curve shows what producers are willing to produce at a given price level.
