How to hide only 2 cells using macros?

Hello,

I have a checkbox for which I have already assigned a macro:

Private Sub CheckBox9_Click()

If (CheckBox9.Value = False) Then
toggle False, False
Else
toggle True, False
End If
End Sub.

Now I want to make some changes in the above code where If I check that check box in addition to the toggle effect it also hides/shows 2 specifice cells "C9 and D9". Is there any way by which I can do it?

Thanks in advance for your help.
