I need help with a page from Macbeth!?

I am supposed to be yzing the plot from the page (Act 1, Scene 7, Lines 1-28) but I am having difficulty coming up with ideas. This is the page where Macbeth and Lady Macbeth are discussing their plan to kill Duncan so Macbeth can become King. I am allowed to use quotes from the rest of the play to help support my ysis. Please help me come up with some ideas for this! Most help gets best answer!
