Where would you plot say, 1+.5i on the plane? I would say at 2- ary point (1, .5), right where x = 1 and y = .5. Say draw a little filled circle at said coordinates in the 2-ary plane where:

So, you try to embed it all in the real line? So, why even have your y axis showing in your graphic? Show me a single point, color it yellow, on your real line that shows the plotted point 1+.5i.

Point 1+5i is A(-4,0).

Any answer?

 I don't understand your answer.
What is 1+.5i. ?

Humm... When I see 1+.5i, I think of plotting x, y point (1, .5) on some graph paper, a little dot or something where origin would be at point (0, 0), or 0+0i.
(1, .5) is x component at 1 and y component at .5. You have used graph paper and a ruler before, right?
