Final answer:

Answer= -2. The imaginary component of the complex number 7-2i is -2 and it is represented by the coefficient of the imaginary unit i.

Step-by-step explanation:

The complex number a + bi has a real part called a, and an imaginary part called b, which is the real number. To be clear, the imaginary part is b, not bi; that is, it does not contain a factor i. The imaginary component of a complex number is the coefficient of the imaginary unit i. For the complex number 7-2i, the imaginary component is the number that appears before the i, which is -2. Therefore, the imaginary component of the complex number 7-2i is -2.
