It looks like you have already done the hard part of the question..(the equation)
If we let time 0 be 7AM. We know at this time we have 6 inches of snow (this is like the y-intercept) the rate of 0.5 is the slope as for every hour we go up 0.5 inches.
The graph looks like this:

Now at 11PM the night before, how many hours passed to get to time 0 (7AM)?
If you think about it long enough 7+1=8 hours passed (so our x value is -8)
All we need to see is what the y value is when x=-8
This could be seen on the graph, but if you are like me and your graphs aren't perfect like the computer shows them... theres another way




So 2 inches will be there at 11PM the night before.
MENTAL CHECK: If you ended up with a negative number, thats not good.. theres no such thing as a negative amount of snow... our answer passes the mental check!
