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.

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.
