In which quadrant is the number 6 – 8i located on the complex plane?

 The given number is located in Quadrant IV.

Step-by-step explanation:  We are to find the quadrant in which the number (6 - 8i) located on the complex plane.

We know that a complex plane is treated as a two-dimensional plane, where the real part of the number is treated as the x-coordinate and the imaginary part is treated as the y-coordinate.

So, if 'x' and 'y' are positive, then

x + yi  =  (x, y)          Quadrant I

-x + yi  =  (-x, y)         Quadrant II

-x - yi   =  (-x, -y)        Quadrant III

x - yi   =   (x, -y)         Quadrant IV

Given number is

(6 - 8i) = (6, -8).

Therefore, the given number is located in Quadrant IV.

i belive those are the ones that are under 90 degreese.
