Answer 1

@confluxepic can you help me?

Answer 2

@TheSmartOne can.

Answer 3

okay.

Answer 4

Just plug them in..let's try the first one.

3x + y > -8

(-3, 0)

3(-3) + 0 > -8

What's 3 * -3? @doresmith

Answer 5

-9

Answer 6

i think (-3,0) is out.

Answer 7

Yep, that gives us:

-9 > -8

-9 isn't greater than -8, so you're right, it's out.

Answer 8

Now let's try (–2, –1):

3(-2) - 1 > -8

Can you multiply 3 * -2?

Answer 9

-6

Answer 10

Yep, that gives us:

-6 - 1 > -8

Can you subtract -6 - 1?

Answer 11

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

Answer 12

Okay, so that gives us:

-7 > -8

This is true, so that means (-2, -1) is a solution.
