Question

Think about plotting points in the complex plane to represent the following numbers: -3+8i, 4i, 6, 5-2i. (on the horizontal axis, on the vertical axis, quadrant 1, quadrant 2, quadrant 3, quadrant 4)

Answer 1

-3 + 8i: quadrant II

4i: on the vertical axis

6: on the horizontal axis

5-2i: quadrant IV

ON EDGE :)

Answer 2

For this case we represent in the complex plane numbers of the form:
a + bi
Where,
a: real part
bi: imaginary part
We represent the real part on the x axis.
We represent the imaginary part in the y axis.
Therefore, for the following numbers we have:
-3 + 8i: quadrant 2
4i: on the vertical axis
6: on the horizontal axis
5-2i: quadrant 4
