What suggests that a blood agar plate contains Streptococcus pyogenes?

Blood agar plates are examined for the presence of colonies of -hemolytic bacteria in order to recognize S. pyogenes in clinical samples. S. pyogenes colonies typically have a dome-shaped, smooth or moist surface, and clear margins after 24 hours of incubation at 35-37°C.

You should anticipate seeing by the sensitivity to bacitracin if Streptococcus perogenous is inoculated to a blood agar played with a tax or a disk.
