Hello!
The slope is the difference in the y-values divided by the difference in the x-values. For our first point, we get -1-1/ =-2, which is equal to 1, so it is not our slope.
For (1,1) we have -1-1/0-1, which is equal to two.
Therefore, our answer is [tex] \boxed {B) (1,1)} [/tex]
I hope this helps!
