We only need 2 points to identify a linear function. They gave us four. The function is. Y=x+1. The point that's NOT on that line is (1,0).

In order for something to be a function, it cannot have an x-value repeated. Therefore, (1,0) cannot be a possible ordered pair because the function already has a point at x=1 (1,2).
