In some cases, we will be asked to plot complex numbers a + bi on the complex plane. To perform this action, we first set up a complex plane. We will use our normal coordinate plane and label the vertical axis as the imaginary axis and the horizontal axis as the real axis. From there, we will find the meeting point of the real part (a) on the real axis and the imaginary part (b) on the imaginary axis

Test Objectives
• Demonstrate the ability to sketch a complex plane
• Demonstrate the ability to graph a complex number
