y = - 5x + 1
y = - 5x + 1

We can see that when x=0, y=1.
y = -5*0 + 1=1
(0,1)

Then we need try several points.
(–2, 11)
11=-5(-2)+1 = -11 True

(1, -4)
-4=-5*1 +1 -4 True

It looks like we have 3 points in A. So, the answer is A.
We can check other points(solutions) using the same way if we want.
