Final answer:
The complex number -5-i has a real part of -5 and an imaginary part of -i, with 'i' representing the square root of -1.
Step-by-step explanation:
The complex number -5-i consists of two parts: a real part and an imaginary part. In this complex number, -5 is the real part, which represents a point on the real number line, and -i is the imaginary part,
where i is the imaginary unit that satisfies the equation i2 = -1. The imaginary part represents a point on the imaginary axis in the complex plane.
