@TheSmartOne can.

anonymous · Answer

okay.

anonymous · Answer

Just plug them in..let's try the first one.

3x + y > -8

(-3, 0)

3(-3) + 0 > -8

What's 3 * -3? @doresmith

anonymous · Answer

-9

anonymous · Answer

i think (-3,0) is out.

anonymous · Answer

Yep, that gives us:

-9 > -8

-9 isn't greater than -8, so you're right, it's out.

anonymous · Answer

Now let's try (–2, –1):

3(-2) - 1 > -8

Can you multiply 3 * -2?

anonymous · Answer

-6

anonymous · Answer

Yep, that gives us:

-6 - 1 > -8

Can you subtract -6 - 1?

anonymous · Answer

-7, sorry it took so long, i got hungry.

anonymous · Answer

Okay, so that gives us:

-7 > -8

This is true, so that means (-2, -1) is a solution.
