Complex Conjugates in Complex Plane

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)

Very cool. I will do this and show my work on my next day off. Thanks again.

do not use term "becomes:

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

Ok. However, my answer for each one is correct.

Yes?
