Question

Which quadrant is the number –14 – 5i located on the complex plane? I / II / III / IV

Answer 1

The complex plance is just like the trigonometric plane except the case is just the x plane pertains to the imaginary part of teh number and the y axis pertains to the real part of the number. In the number -14-15i, x axis is negative and y axis is also negative. Hence the number should belong to quadrant III. 

Answer 2

The first thing you have to take into account is the definition of the axis in the complex plane.

We have then:

The vertical axis represents the imaginary part.

The horizontal axis represents the real part.

We then have the following number:

-14 - 5i

Since the real part and the imaginary part are negative, then the number is located in the third quadrant of the complex plane.

Answer:

Quadrant III.
