I would think the answer would be C, y=-3x+2 because you first have to find the slope:

5+1                                                  y-y
___    because the formula is   ___
-1-1                                                  x-x

That would leave you 6/-2 or -3 for the slope. Then, you plug in the points for x and y:

y+1=-3(x-1)
y+1=-3x+3
  -1          -1
________
y=-3x+2

I hope this helps!
