Work Step by Step

See p. 602, Graphing Complex Numbers The complex plane is determined by the real axis and the imaginary axis. To graph the complex number a + bi, we plot the ordered pair of numbers (a,b) in this plane The complex conjugate of $z=a+bi$ is $\overline{z}=a-bi.$ ----------- $z=-5+6i$ Plot $(-5,6)$ in the complex plane. $\overline{z}=-5-2i$ Plot $(-5,-6)$ in the complex plane.
