# How do you plot 4i on the complex plane?

Aug 29, 2016

$4 i$ is represented by the point $\left(0 , 4\right)$ on the complex plane

#### Explanation:

Complex nmbers consist of Real part and an Imaginary part in the form: $z = \left(a + b i\right)$ $\left\{a , b\right\} \in \mathbb{R}$

The complex plane is simply an $x y$ plane where the $x$-axis represents the Real coordinate ($a$) and the $y$-axis represents the Imaginary coordinate ($b$).

In this example: $z = 4 i \to a = 0$ and $b = 4$

Therefore $4 i$ is represented on the complex plane by the point $\left(0 , 4\right)$
