Select the pair of equations whose graphs are perpendicular.
A.) 5x - 8y = 9
12x - 5y = 7
B.) 3x + 6y = 8
y = 3x - 8
C.) y = 2x - 7
x + 3y = 3
D.) 2y = -3x + 5

Given the linear equation 3x + y = 5, find the slope of its graph.
-3
-5
3
5

Given the linear equation 3y + 4x =12, find the y-intercept.
Option A: -4/3
Option B: -4
Option C: 4/3
Option D: 4

- anonymous

y-intercept is 4

- anonymous

Write an equation in slope-intercept form for the line passing through (-1, 5) and (5, 8). Option A: y= -1/2x +11/2 Option B: y= -1/2x - 11/2 Option C: y=1/2x - 11/2 Option D: y=1/2x +11/2

D

- anonymous

YAY!!! Thanks for the fan!!! =) (= <3

- anonymous

Solve the system of equations. 3x + 3y = -10 x + 3y = 0 (Points : 5) Option A: x = -3/2; y = -1/2
Option B: x = 3; y = 1
Option C: x =-5; y = 5/3
Option D: x = 3; y = -5
no problem!! and thanks for helping~

- anonymous

'Tis C.
And you're welcome

- anonymous

Solve for x.
x - 1/12 = 7/2
(Points : 5) 3
Option A: x= 4- (the fraction is supposed to be 4 and 3 7ths)
7
Option B: x = 6
Option C: x = 41
Option D: x = 43

this is the last question

- anonymous

wait i typed the question wrong

- anonymous

let me re-type it

- anonymous

okay

- anonymous

oh wait never mind its right ahaha

- anonymous

- anonymous

never mind its 43

i typed it in wrong at first

- anonymous

ohhh ok

- anonymous

wait which one was it?

- anonymous

It's x=43
in other words its Option D

- anonymous

ohh ok, thank you!!

- anonymous

i got 12/14 right so thanks!!

- anonymous

you're welcome!!! =) (= <3

- anonymous

Happy to help!!!

It's A. (-1,7)

Also known as the intersection point

- anonymous

second one!

##### 1 Attachment

- anonymous

it's the intersect (where they meet)

- anonymous

so is it C?

- anonymous

yes

- anonymous

what about this?

##### 1 Attachment

haha me too, i wasn't doing so good so i had to take these online tests to bring up my grade and i have alot to do -__- lol

- anonymous

Yeah but I love them all equally and I wouldn't traded them for anything (Not even the Akatsuki from Naruto Shippuden)

- anonymous

i used to have a chinese pug

- anonymous

that's why I'm doing Florida Virtual School. Well actually I had and have very good grades but I was bored in school so yeah

- anonymous

OH!!! I like pugs they're so cute

- anonymous

I have 3 Boxers and 2 English bulldogs (they're ALL girls) (Dad doesn't like boy animals)

- anonymous

my grades were getting low because i went to florida for vacation and i had a lot of catching up to do! haha and yeah i do an ohio virtual school

- anonymous

my mom doesn't like dogs at all lol

- anonymous

LOL!!! I Live in Florida!!! That's kinda funny. and ironic

- anonymous

haha yeah!

- anonymous

But seriously it's ACTUALLY called Florida Virtual School (FLVS)

- anonymous

mines called Ohio Virtual Academy (OHVA) from k12

- anonymous

These people come up with such non-creative names don't they

- anonymous

hahaha yes they do

- anonymous

You know something. I've been doing Physics while helping you. I got bored

- anonymous

That's what I do when I get bored with school. I go on here and see if I can help anyone

- anonymous

well thats nice of you! like i have sooooo much to do because it's the end of the semester! i just want the semester to end already!

- anonymous

Which Semester are you in 1 or 2? I'm in semester 2 of Physics. Actually getting ready to do the Chapter test for the last chapter an then all I have left is the Semester exam

- anonymous

right now its the end of the 1st semester. the 2nd semester starts on the 18th

- anonymous

Oh well um. You can move at your own pace in FLVS and so I've already finished semester 1 (I did that before Christmas)

- anonymous

And thankfully there are only 3 chapter in semester 1 and 4 chapters in semester 2 so it's not that hard really

- anonymous

wow that sounds much easier because here we don't move on our own pace and we have like 8 or 9 chapters per semester

- anonymous

Yeah, you see the entire reason that I started homeschooling was because I had to do extra homework because SOMEONE ELSE didn't understand. Gosh I hated have to do more work cause of someone else. Not that it's their fault that they don't understand but I just think that it's unfair to give the kids that know the stuff extra work as well.

- anonymous

yeah that isn't fair and i started homeschooling because the schools here are really bad

- anonymous

Oh that sucks

- anonymous

Hey I got to go take my chapter 7 test for Physics. I'm not logging out in case I need to ask a question but I'm gonna be technically off for a bit okay.

- anonymous

okay :)
