WILL GIVE BRAINLIEST ANSWER!!!!Which of the following points satisfies the inequality 2x - 3y < 1?

(-2,1)
(1/2, 0)
(2, -1)

Answers

Check first one:
2(-2)- 3(1) < 1
-4 -3 < 1
-7 < 1
This is true, let's check others, just to be sure
Check second one:
2(1/2) - 3(0) < 1
1 - 0 < 1
This is false
Check third one :
2(2)- 3(1) < 1
4- 3 < 1
This is false

So answer is (-2,1)
(-2,1) satisfies
2×-2-3×1=-7
-7<1
