Answer 2

Answer:

(5, 6)

Step-by-step explanation:

y = x - 1

(9, 8)

y = x - 1

8 = 9 -1

8 = 8 (this point is on the graph)

(8, 7)

y = x - 1

7 = 8 - 1

7 = 7 (this point is on the graph)

(5, 6)

y = x - 1

6 = 5 - 1

6 = 4  (this point is not one the graph

(4,3)

y = x - 1

3 = 4 - 1

3 = 3 (this point is on the graph

Hope this helps!
