Answer:
(2,-1)
(-2,1)
(0,1)
Step-by-step explanation:
Let's plug in the points given and see which satisfy it (make it true).
2x+3y>=-1
Test (2,-1)
2(2)+3(-1)>=-1
4 + (-3)>=-1
1>=-1 This is true 1 is greater than -1 so (2,-1) works!
Test (-6,0)
2(-6)+3(0)>=-1
-12 + 0 >=-1
-12 >=-1 This is not true. -12 is not greater than -1.
Test (-2,1)
2(-2)+3(1)>=-1
-4 + 3 >=-1
-1 >=-1 This is true. -1 does equal -1.
Test (0,1)
2(0)+3(1)>=-1
0 + 3 >=-1
3>=-1 This is true. 3 is greater than -1.
Test (0,-1)
2(0)+3(-1)>=-1
0 + (-3)>=-1
-3>=-1 This is false. -3 is not greater than -1.
