Answer 1

@STARSHIP

Answer 2

Do you mean \(y=\frac{x}{3}-2\)?
Hint:
For an equation of a line y=ax+b, a is the slope, b is the y-intercept.
Since the y-intercept of all 4 graphs are different, it would be relatively simple to locate your answer where b=2, and double check with the slope a=1/3.

Answer 3

@Algorithmic do you understand this?

Answer 4

@Lyrae

Answer 5

Do you remember, what I told you yesterday? You can apply the same concept here.

Answer 6

Well i think it would be A looking at how it crosses through the y intecept

Answer 7

Is that wrong?

Answer 8

Close, but that is incorrect. Remember, rise over run?

Answer 9

You rise up by one, and run by three.

Answer 10

Yeah ok i see is it B?

Answer 11

No, B cannot be it remember it has a y-intercept of \(-2\).

Answer 12

Ok sorry lemme look 1 more time

Answer 13

No worries. Take your time.

Answer 14

I think it would be C mainly because it goes through a positive 2 unlike D which goes through a negative 2

Answer 15

And if you look at the rise and run they are both equal

Answer 16

Am i right???

Answer 17

o_O

Answer 18

You want it to go through \(-2\) as that is your y-intercept.

Answer 19

@mathmate b should be -2

Answer 20

Oh ok that made me look stupid :/ sorry so D is the answer could you help on a couple more?

Answer 21

find x-intercept and you are done

Answer 22

@Algorithmic are you busy?

Answer 23

Yes. Sure, post a new question and tag me.

Answer 24

I can let you be if you need

Answer 25

Ok then thanks

Answer 26

@algorithmic thanks, that was an oversight! b= -2 it is.
