Answer:

hello :  (2 ; 9)

Step-by-step explanation:

y > 3x+2......(1)

put : x and y in : (1)

1) for : (-2 ; -7)   where x = - 2  and y = -7  so :-7 > 3(-2)+2

-7 > - 4  ...... false

2) for : (-1 ; -5)   where x = - 1  and y = -5  so :-5> 3(-1)+2

-5 >  -1  ...... false

3) for : (2 ; 8)   where x =  2  and y = 8  so :8 > 3(2)+2

8 > 8  ...... false

4) for : (2 ; 9)   where x =  2  and y = 9  so :9 > 3(2)+2

9 > 8  ...... true

the ordered pairs is a solution to this inequality  y > 3x+2 :  (2 ; 9)
