Credo infiniti in quanto sono tutti i punti appartenenti alla retta y=-x+13 nel piano di Gauss.
Le y sono Im(z) e le x Re(z).
Guarda se è chiaro.

Sì, come dice Matthew, non ti confondere: z=x+iy significa che x e y sono quote/coordinate nel piano cartesiano, e quindi numeri reali.
x+iy è un numero complesso in forma cartesiana, ma x+y=Re(z)+Im(z) cioè due numeri reali.
Quindi Re(z)+Im(z)=13 è proprio una relazione tra coordinate.

Spero che ora sia più chiaro. ^__^
