[G4] Can I update my OS with this?

[Ascender]

Hello all

I have a G4 PowerMac and am trying to update my Operating System to 9.2.8.
I only want to update this far as my other software would need to be updated
beyond that and I can't afford it at this time.

I ordered software from OperatorHeadGap.com   The installation discs say
'eMac Mac OS; Install 1 and 2'.  Can I install these discs or did I order
the wrong thing?

This is the product I ordered:
