Step-by-step explanation:
y < 3x – 1
y > –x + 4
(4,0) Plug in x=4 and y=0 in the given inequality
0 < 3(4) – 1 True
0 > –4 + 4 False
(1,2) Plug in x=1 and y=2 in the given inequality
2 < 3(1) – 1 False
2 > –1 + 4 False
(0,4) Plug in x=0 and y=4 in the given inequality
4 < 3(0) – 1 False
4 > –0 + 4 False
(2,1) Plug in x=2 and y=1 in the given inequality
1 < 3(2) – 1 True
1 > –2 + 4 False
All the given ordered pairs makes the inequalities false
