y = b - x
So what is y equal to when x=1?

No prob @42cookiethere 
y=b-1 when x=1
do u understand that?

I'm trying to, lol! @sdfgsdfgs

You simply substitute by each x's and y's value in the given equation you will get for the first two values sth like this respectively :
11 = b - 1
10 = b - 2
then you could easily get b which is equal to 12
try the other values by hand and let me know if you got it well as I explained :)
