(2, 1)
(1, 1)
(0, 1)

Answer 1

(1, 1)

Answer 2

thank you ademm(:

Answer 3

Well let's first get the equation. We use point-slope. y-y1=m(x-x1).
y+1=2(x-0) =
y+1=2x+0 Now we subtract both sides by 1
y=2x-1. Now all we have to do is put in those 3 values and see which one equals out.
Once you do, the only that works is (1,1) and that's your answer.
