Question

time is measured along the x - axis. what is measured along the y - axis?
employment levels
prices
economic output

Explanation:

In typical economic graphs (like aggregate supply - aggregate demand or production - time graphs), when time is on the x - axis, economic output (such as GDP, total production) is a common variable measured on the y - axis. Employment levels, prices, and demand are not the standard variable for the y - axis when time is on the x - axis in the context of measuring the overall economic production over time.

Answer:

C. economic output
