Question

why is income line 45 degree​

Answer 1

Answer:

Answer:The 45-degree line shows where aggregate expenditure is equal to output. This model determines the equilibrium level of real gross domestic product at whichever point aggregate expenditures are equal to total output. In a Keynesian cross diagram, real GDP is shown on the horizontal axis.

The reason why diagrams have this 45-degree line is that for every point on the line, the value of whatever is being measured on the x-axis is equal to the value of whatever is being measured on the y-axis. ... Equilibrium national income occurs where Y = E, and this would be every point on the 45 degree line.
