@galaxyzstarz

GalaxyzStarz:

Ah, more graphing, give me a moment! :)

L2doll:

YEa :(

GalaxyzStarz:

Here's the graph I created, can you use this to figure out which to eliminate?

L2doll:

yes its 100% C,D

L2doll:

So was i a correct

ShoaibChaudhry:

Yes you can use a site called demos its a grpahing site that can help you

L2doll:

yea ik i was asking soldier if I was supposed to eliminate C,D

ShoaibChaudhry:

Yes you would have 2

L2doll:

@galaxyzstarz you there??

ShoaibChaudhry:

U could dm maybe

L2doll:

i think he's working it out.

GalaxyzStarz:

Yes, eliminate those.

GalaxyzStarz:

Now, which do you choose of A.) or B.)?

L2doll:

ok

L2doll:

hmm

L2doll:

A

GalaxyzStarz:

Why A.)?

GalaxyzStarz:

Let's take a look at the graph again.

Actullay its B let me explain

L2doll:

welll point (3,2) parallel to y= 3x-7 slope = 3 y=mx+b 2= 3(3)+b, 2=9+b, -9-9, -7=b SO that means that the answer is y=3x-7

L2doll:

So was i correct

L2doll:

@galaxyzstarz

GalaxyzStarz:

Yes, correct.

L2doll:

Awesomm

L2doll:

Do you mind checking my answers i completed the test I just ned conformation

L2doll:

there are 15 questions

L2doll:

@galaxyzstarz

L2doll:

sooo....

GalaxyzStarz:

I guess.
