Why don't you substitute in the given points until you find one that makes a false statement.
I will do the first one for you:
$$0+2(4)\le 8$$
$$8\le 8$$
That is true since 8 is equal to 8

Now you try the others.

so Im not sure if its correct but I think its (6,0)???????

mertsj · Answer

$$6+2(0)\le 8$$
$$6\le 8$$
That says that 6 is less than or equal to 8.
Since 6 IS less than 8, that is true.
