Chapter 8 - 8.5 - The Complex Plane - 8.5 Exercises - Page 603: 7



Work Step by Step

Note that when graphing in the imaginary plane, the vertical axis is the imaginary axis. Also, note that when graphing in the complex plane, the horizontal axis is not the x-axis but is rather the real axis. Thus, when given an expression in the form $a+bi$, we go a units along the real axis and b units along the imaginary axis. Knowing this, we see that the point should be 2 to the right and 0 up. This matches graph c.
