Summary: The number -14 – 5i is located in the third quadrant on the complex plane.
Step-by-step explanation: We are given a point located on the complex plane and we are to select the correct complex number that is represented by this point. We can see that the co-ordinates of the point on the plane are (3, -4).
A complex number can be visually represented as a pair of numbers (a, b) forming a vector on a diagram called an Argand diagram, representing the complex plane. Re is the real axis, Im is the imaginary axis, and i is the “imaginary unit”, that satisfies i2 = −1.
Thus, complex numbers are naturally thought of as existing on a two-dimensional plane. Geometric representation of z and its conjugate z in the complex plane The complex conjugate of the complex number z = x + yi is given by x − yi. It is denoted by either z or z*. [43]

What is the absolute value of a complex number?
An imaginary number is a real number multiplied by the imaginary unit i, which is defined by its property i2 = u22121. The square of an imaginary number bi is u2212b2. For example, 5i is an imaginary number, and its square is u221225. By definition, zero is considered to be both real and imaginary.
In what quadrant is the number located on the complex plane?
In a complex plane, X-axis is used to locate the real part of the complex number and Y-axis is used to locate the imaginary part. So the point (6, -8) will lie on the IV quadrant. Therefore, the number lies in the IV quadrant.
