A. (-4, 0)
B. (-1, 0)

D. (0, -4)
A. (-4, 0)
B. (-1, 0)
C. (-2, -1)
D. (0, -4)

You just need to test the inequality (y > -2x - 3) with the four possible solutions provided.
A. (-4,0) ==> 0 > -2(-4) - 3 ==> 0 > 5 is FALSE
B. (-1,0) ==> 0 > -2(-1) - 3 ==> 0 > -1 is TRUE
C. (-2,-1) ==> -1 > -2(-2) - 3 ==> -1 > 1 is FALSE
D. (0,-4) ==> -4 > -2(0) - 3 ==> -4 > -3 is FALSE
A, C, and D are not solutions to the inequality. Only B is a solution.
A. (-4,0) ==> 0 > -2(-4) - 3 ==> 0 > 5 is FALSE
B. (-1,0) ==> 0 > -2(-1) - 3 ==> 0 > -1 is TRUE
C. (-2,-1) ==> -1 > -2(-2) - 3 ==> -1 > 1 is FALSE
D. (0,-4) ==> -4 > -2(0) - 3 ==> -4 > -3 is FALSE
A, C, and D are not solutions to the inequality. Only B is a solution.

You ment correct right? To solve you plug in the coordinated numbers. (x,y) for ex: y>-2x-3 (-4,0)
So -4 is x and 0 is y. 0>8-3 then simp. 0>5
That's how you solve.
The correct answer is B
So -4 is x and 0 is y. 0>8-3 then simp. 0>5
That's how you solve.
The correct answer is B

A,C, and D are not solutions.
just plug in the ordered pairs into the equation and check to see if it fits the inequality.
ex. plug A into the equation. u get 0 > 5, which is not correct etc...

Answer: D
Plug them in:
-4 > -2(0) - 3
-4 > 0-3
-4 > -3 is False so that's the answer.
Plug them in:
-4 > -2(0) - 3
-4 > 0-3
-4 > -3 is False so that's the answer.
