$| - 2 i | = 2$ $abs(-2i)=color(green)(2)$

The absolute value of a complex number is its distance from the origin in the complex plane.

$- 2 i$ $-2i$ is a point on the complex plane $2$ $2$ units below the Real axis and on the Imaginary axis (its Real component is $0$ $0$ ).

Therefore its distance from the origin is $2$ $2$
