Example 1.2.4 (b): Complex numbers in the plane

Let u = 3 - 4i and v = i, and w = -2. Draw -u, -v, -w and then describe how -z looks in relation to z for arbitrary complex numbers.
Context Context
u=3-4i (blue) and -u=-3+4i (red) v=i (blue) and -v=-i (red) w=-2 (blue) and -w=2

Thus, in general -z is the vector z reflected around the origin (0,0).
