Answer to Question 1

There appears to be a positive relationship between the number of dinners served and the number of overnight guests.
The Y intercept b0 = 120 is meaningless in this situation.
The slope b1= 0.6. This means that for each additional overnight guest, we would expect 0.6 additional dinners to be served.

Answer to Question 2

C
