there should be options given

Answer 2

(A). 2i (B). i-1 (C). 1-i (D). 2-3i

Answer 3

I think it's (B).

Answer 4

\(\large \begin{align} \color{green}{\normalsize \text{so first try to convert these points like this and see it in the graph} \hspace{.33em}\\~\\
0+2i \implies (0,2) \hspace{.33em}\\~\\
-1+i \implies (-1,1) \hspace{.33em}\\~\\
}\end{align}\)

Answer 5

It's not either of those.

Answer 6

\(\large \begin{align} \color{black}{
1-i \implies (1,-1) \hspace{.33em}\\~\\
2-3i \implies (2,-3) \hspace{.33em}\\~\\
}\end{align}\)

Answer 7

(C).

Answer 8

yes it \(\huge (C.)\) option \(\large (B.)\) was tricky to confuse

\(\large \begin{align} \color{black}{
i-1=-1+i \implies (-1,1) \hspace{.33em}\\~\\

}\end{align}\)
