Can you do 38 as a guide for me to do the rest on my days off? Thank you.

You find the complex conjugate simply by changing the sign of the imaginary part of the complex number.
Thus the complex conjugate of 2+3i is 2 - 3i.
By using the x axis as the real number line and the y axis as the imaginary number line you can plot the value as you would (x,y)

do not use term "becomes:

if you have complex number 2+3i, its conjugate is 2-3i
