Ima wait for someone to help me.
Out of curiosity, what do you think the answers are?
#1 false -- a+bi is imaginary if a=0 and b≠0
#2 true
#3 false -- i^2 = -1 ... i = √-1
#4 true
looks like you need to review the topic -- these are the bare basics
#2 true

Imaginary numbers shouldn't exist.
Thank you for your response! I really needed it!
This helped me greatly.
I don't agree with the answer to #4
A number such as 5 + 4i cannot be graphed on the real xy coordinate plane.
We need the Argand plane, where the horizontal axis would be the a value of
a + bi, and the vertical axis would be the b value of a + bi
