Complex plane can be thought to be modified Cartesian plane, with the real part of a complex number represented by a distance along the x-axis, and the imaginary part by a displacement along the y-axis. The concept of the complex plane allows a geometric interpretation of complex numbers. The real part of complex numbers is represented in the x-axis and Imaginary part in the y-axis

__The Cartesian Plane:__

The normal Cartesian plane, with x-axis and y-axis, is also used to represent the Complex Plane. The x-axis is the **Real axis** and y-axis is the **Imaginary axis** in the Complex Plane. The Diagram below shows the complex plane of

**z = a + ib** and its conjugate is **z = a – ib.**

Examples shown in the Diagram below are

a. **z = a + ib** b. **-z = a – ib **c**. z = a – ib. (**

__conjugate__

__)__The plot of the complex numbers **z = 4 + 3i **and** z = -5 – 4i **on the complex plane is as shown below

Complex numbers can be represented graphically on the complex plane. The resulting graphical representation of complex and Real numbers is called **Argand Diagram.**
