Answer:
2
Explanation:
Slope = change in y (rise) / change in x (run)
if you pick any two dots and you count the rise over the run, the answer will always simplify to two.
Ex: (0, 1) (-1, -1)
The point (0, 1) is three units up from the point (1, -1)
The point (1, -1) is 2 units from (0, 1) on the x axis
The fraction is 2/1, but if you simplify that it will be 2
