Answer 1

Quick question. In an ordered pair, do you know which number is x and which number is y?

Answer 2

No i dont think so hahah

Answer 3

An ordered pair is always written like this
(x, y)
The first number is x and the second number is y. So for example:
(3, 5) means that x is 3 and y is 5.

Got it?

Answer 4

yeah i knew that .

Answer 5

Cool. Good =)
So, look at the first ordered pair they give you. Plug x and y in, and show me what you get.

Answer 6

well I don't understand the equation haha.

Answer 7

y < 2x - 8
< means "is less than"
plug y in. Plug x in. See if it is a true statement.

Answer 8

OH okay I think i got it know

Answer 9

Oh yeah? Can I see your attempt please?

Answer 10

5> 2*-10 -8

Answer 11

You plugged things in in the right spot, but you changed the < to a >. Don't do that.
5 < 2*-10 -8
Cool, so just do a little bit of math and then tell me if that's true or not.

Answer 12

I didn't mean to change those.

Answer 13

(10, 5) is that the right answer?

Answer 14

never mind.
