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
$\overline{z}=a-bi.$
-----------
$z=8+2i$
Plot $(8,2)$ in the complex plane.
$\overline{z}=8-2i$
Plot $(8,-2)$ in the complex plane.
