Which of the following points is a solution of the inequality y

Question

Which of the following points is a solution of the inequality y < -|x|?


(1, -2)
(1, -1)
(1, 0)

debbieg · Answer

try each point in the inequality, and see which one is a true statement.

i dont even know how to do this

debbieg · Answer

In an ordered pair, the first number is the x coordinate, and the second number is the y coordinate. 

So for the first ordered pair, (1, -2), you have x=1 and y=-2.

Plug those values into your inequality y < -|x| and see if it is TRUE or FALSE.

debbieg · Answer

For example, if I wanted to check the ordered pair (-2, 5) in your inequality, I would plug in:
x=-2, y=5

And I get

5 < -|-2|  which, since |-2|=2 gives me:
5 < -2
which is FALSE. Therefore, (-2, 5) is NOT a solution.

Now you try it with your answer choices, see for which one you get a TRUE statement. That's the one that is in the solution set.
