Question

What complex number is represented on the graph?

4 − 5i
4 + 5i
5 − 4i
5 + 4i

Answer 1

5-4i

Explanation:

On the real axis we move 5 units in the positive direction (to the right, that is why we have 5, not -5), and then on the imaginary axis we move 4 units in the negative direction (down, that is why we have -4i, and not +4i).
