Axes and Properties of the Aggregate Demand Graph (Figure 3.12)
The aggregate demand function is plotted on a graph where the horizontal axis represents aggregate output or income (Y) and the vertical axis represents aggregate demand (AD). As shown in Figure 3.12, the line representing aggregate demand has two key properties: its vertical intercept is equal to the level of autonomous demand (), and its slope is determined by the marginal propensity to consume ().

Vertical Intercept of the Aggregate Demand Curve
Slope of the Aggregate Demand Curve in the Simplified Model
In an economy, total planned spending is the sum of consumption and a fixed amount of planned investment. If business leaders become more pessimistic about the future and consequently reduce their planned investment spending, how would this change be depicted on a graph with total planned spending on the vertical axis and aggregate output on the horizontal axis?
Deriving the Aggregate Demand Curve's Properties
Evaluating an Economic Claim with a Graph
In an economic model, total planned spending is the sum of consumption and planned investment. Consumption spending is known to increase as total income rises. Initially, planned investment is assumed to be a fixed amount that does not change with income. If this assumption is changed so that planned investment also increases as total income rises, how would the graphical representation of the total planned spending curve be affected?
In a simple economic model, total planned spending (AD) is given by the equation AD = 150 + 0.6Y + 250, where Y is aggregate output. Match each conceptual component of this model's graphical representation with its correct numerical value or description.
On a graph with total planned spending on the vertical axis and aggregate output on the horizontal axis, the line representing the consumption function and the line representing total planned spending (aggregate demand) will have different slopes because planned investment is included in aggregate demand.
Interpreting the Aggregate Demand Graph
An economist wants to draw the aggregate demand curve for a simple economy on a graph with aggregate output on the horizontal axis. They start with a pre-existing line representing the consumption function and are given a single, constant value for planned investment. Arrange the following steps in the correct logical sequence to accurately construct the aggregate demand curve.
In a simple economic model, the consumption function is represented by a line with a slope of 0.75. If a constant level of planned investment is added to this consumption function to derive the total planned spending (aggregate demand) curve, the slope of the resulting aggregate demand curve will be ____.

Consider two different economies, A and B, represented by two aggregate demand (AD) lines on a graph where the vertical axis is aggregate demand and the horizontal axis is aggregate output. Line AD_A starts at a higher point on the vertical axis than line AD_B, but line AD_B is steeper than line AD_A. Based on this graphical representation, which of the following statements is most likely true?
