Question

How do you plot `-6i` on the complex plane?

Answer 1

There are two possible points that could be referred to as `-6i`
(see below)

Explanation:

`-6i` would most commonly be the point `color(red)(""(-6,i))` or `color(red)(""(6,1))` on the Complex plane,
but it might also be `6(-i)` the point `color(blue)(""(6,-i))` or `color(blue)(""(6,-1))` on the Complex plane.
