Question

A complex number z = a + bi has two parts: a is the __________ part, and b is the
__________ part. To graph a + bi, we graph the ordered pair in the complex
plane.

Combination of a real number and an imaginary number. They are numbers of the form a + b , where a and b are real numbers and i is an imaginary unit. Complex numbers are an extended idea of one-dimensional number line to two-dimensional complex plane.
