1. All we need to do here are figure out the coordinates of each of our points, and
2. then recognize that the horizontal one is a and the vertical one is b. So for
3. example, we know that point a has the coordinates 3,5, so the complex point it
4. represents is 3 plus 5i. Similarly b is 5+3i. Let's look at a point in a
5. different quadrant, maybe point f over here. The coordinates of f are negative
6. 5, negative 3, so that represents the number negative 5 minus 3i.
