Answer 2

(x,y) are your points, plug in x get output y

Answer 3

3=3x
Lets see (0,3)

3=3(0)
3 = 0 ?
does that make sense?

Answer 4

Yes, it does

Answer 5

So, the answer id B?

Answer 6

Well think about it, look at the first option they give, (3,0)
3=3(3) => 3 = 9 that's not right. You want the output to be equal on both sides, but if you had (1,3)
3=3(1)
3=3 that's right!

Answer 7

So it's D?

Answer 8

Try it yourself...

Answer 9

Plug in the values, see if it makes sense to you.

Answer 10

No it seems like the answer is C... I think. I'm almost positive.

Answer 11

Can you prove it?
