Economic Definition of axes. Defined.

Offline Version: PDF

Term axes Definition: Two number lines that are joined at a right angle such that they intersect at their zero points (called the origin). The vertical axis is by convention termed the Y-axes and the horizontal axis is termed the X-axis. These axes are used to locate or plot pairs of numbers in coordinate space, one value for the X-variable coordinate and a corresponding value for the Y-variable coordinate. More often than not, coordinate number pairs are used to plot relationships that can be connected by one or more lines. This line construction procedure is one of the more powerful tools used by economists. Economists typically analyze relationships between two variables, such as price and quantity demanded. By letting one axis measure price and the other measure quantity demanded, these axes form the framework, the guidelines if you will, for constructing a demand curve (the relationship between price and quantity demanded). Once we have an abstract relationship graphed out, then it can be used to perform all sorts of economic analysis.
