Please can someone help me with these FP1 questions, it's do with drawing argand diagrams

|Z-3-4i| = 4

|Z| = |Z - 8i|

Thanks

First is a circle, second is a bisectior

I thought the first one was a straight line of some sort??

Pretty sure it's a circle centre 3,4 radius 4

Sub in x+iy for Z and you can get a cartesian out

|(x-3) + (y-4)i| = 4
Sqrt((x-3)² + (y-4)²) = 4
(x-3)² + (y-4)² = 16

Cba to get my notes though to be honest

I am going crazy trying to download all the Edexcel question papers, mark schemes and examiner reports and then sorting them in a tidy manner.
I would greatly appreciate it if someone could send me .zipped file all the above!

If it's not possible, I shall try to assemble this myself and then I will post it here.

Can I ask does the examiner report help in anyway?

I understand for social sciences but for maths???

can someone provide a reasoning

i looked at a few and it simply points what they did wrong like forgetting to write the answer etc
