Graph of a complex

Graph of a complex

We will draw the graph of a complex

Given a complex number z=a+b\cdot{i}=(a, b) \in \mathbb{R} x \mathbb{R} is an ordered pair of real numbers, represented by the point (a, b) on the XY plane, called complex plane

The dot (a, b) is called the z-complex number

Example of graph of a complex

Given the following complex we want to represent:

z=(-3)+4\cdot{i}

We get the following graph:
