Plot A) thru B) from the OP and label the points.

Your work with complex numbers will get MUCH harder from this point.

Do you know how to plot (3, -2) on a graph?

So use an xaxis of -4i to 4i and a y axis of -1 to 3 then simply plot them?

The instructions are pretty clear to me -

Have you looked in your book? It should have several examples of graphing complex numbers.Graph the following numbers on a complex plane.

No, you have your axes the wrong way around. The x-axis corresponds to the real numbers, and the y-axis to the imaginary numbers. To plot a number [itex]z = a+ib[/itex], you plot (a,b) and you label your real axis (x-axis) as Re(z) and your imaginary axis as Im(z).

Also note that [itex]a = a+i0[/itex] and [itex]ib=0+ib[/itex]
