Consider the complex numbers t = –6 + 4i, u = –5i, w = 4, and z = 3 – 8i. On the complex plane shown, t has been plotted. Question:

A. What are the real and imaginary parts of t? Are the real part and the imaginary part real numbers or imaginary numbers? What does i represent?

B. What are the real and imaginary parts of u and w? Are u and w real numbers or imaginary numbers? What does this tell you about the relationship between real numbers, imaginary numbers, and complex numbers?

C. Plot z on a complex plane.
