Question

What set of equations does this graph go with?
https://www.connexus.com/content/media/369615-772011-13945-PM-333188703.png

5x − y = 7
2x − y = 0

5x − y = 7
2x + y = 0

5x + y = −7
2x + y = 0

5x + y = −7
2x − y = 0

Answer 1

what anime is that pic from? :O

Answer 2

Then I help :D

Answer 3

Vocaloid or Hatsune Miku...I saw that it said that it was a new Vocaloid character coming...lol

Answer 4

lol I got it off a website..that's what it said but I just saved the pic ><

Answer 5

Meh, I would of regcognized her if it werent for the offset >.< ANYHOW!

Answer 6

haha!

Answer 7

For the problem I get confused and I don't really understand on how to solve for these

Answer 8

lets refresh our minds a little bit yes? some nice cold lemon aid from summer *sip*

Answer 9

ok (sipping) lol

Answer 10

Ok, firstly we need to solve these EQUATIONS yes? *sorry ive been playing piano for one hour, which is like staring at a wall for 30*

Answer 11

Yes we need to solve these equations*determined* it's okay :P

Answer 12

5x − y = 7, like for the first one, we need to solve for it and then see if it matches the coorinates, theres two equationss one for each of the lines. OK, then, we first have to find the slope of these lines first so we can know what were looking for, right detective SJninja?

Answer 13

Right!

Answer 14

ok!

Answer 15

hmm..isn't the slope 2/1 for the line on the left?

Answer 16

let me see,

Answer 17

than the one on the right is 5/1..i think

Answer 18

yes! your a genious!

Answer 19

lol

Answer 20

and I see why you cant solve 5x-y=7 :( but not to worry!

Answer 21

so that means that 1 and 2 are definitely not one of the answers..?

Answer 22

right O

Answer 23

so what do we do next/

Answer 24

2,1 and 5,1. hmm.

Answer 25

><

Answer 26

I think we need those things, to solve the equation

Answer 27

right...I have a question. did the slopes become x,y?

Answer 28

it should equal that, therefore...

Answer 29

yes, I just found that out because you cant really...hmm...subtract em? so you just leave me there...or.. with a defenite answer..

Answer 30

ohh

Answer 31

so it's either...hmmm
5x + y = −7
2x + y = 0

5x + y = −7
2x − y = 0

Answer 32

yes! the equation becomes the slope!

Answer 33

so all we need to do now is plug in the slope?

Answer 34

orwe could just find it off by writing it in its form since we already konw it, or I think you mean the same thing.

Answer 35

your way sounds better lol

Answer 36

oh god my hot pockets are burning give me a second....

Answer 37

haha ok >_<

Answer 38

5x + y = −7
2x − y = 0
I put the last one in y = mx + b form and got
y = -2x + 0
....idk if that is supposed to help at all lol

Answer 39

Ok got it!

Answer 40

srry it took so long, so if those things are coordinates for a graph, and y and x is freaking so, lets write em down.

Answer 41

ok

Answer 42

now then, we could say that y= 5x -7 for the first line, lets see if its so.

Answer 43

ok:)

Answer 44

I think that's it!

Answer 45

if its a negative...hmm, yes.. ok and for the second line...

Answer 46

oh snap -_- that's on them both...

Answer 47

eh?

Answer 48

y=2x-0

Answer 49

OMG OMG!

Answer 50

IT is! ok! we know for shure that for the FIRST LINE, y=2x-0!

Answer 51

ahhh

Answer 52

ahhhhh fake! nvm, lying..

Answer 53

HAZAH! awesomness! we did it! lol thanks!

Answer 54

wait..huh?

Answer 55

:S HURAY!

Answer 56

lol here is the pic if you wanted! thanks for helping me!

Answer 57

detective, its been my pleasure working with you!.... Ill c ya in 30 mins....thanks!

Answer 58

no prob!
