Think about plotting points in the complex plane to represent the following numbers: -3+8i

4i

6

5-2i

A coordinate plane is labeled quadrant 1 in the uppercase-right quadrant, quadrant 2 in the uppercase-left quadrant, quadrant 3 in the bottom left quadrant, and quadrant 4 in the bottom right quadrant.
Where is each point located on the graph?
–3 + 8i is
on the horizontal axis
.

4i is
on the horizontal axis
.

6 is
