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 2x - 3y = 4

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

  • anonymous
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
  • anonymous
y-intercept is 4
anonymous
  • 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

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

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~

'Tis C. And you're welcome
anonymous
  • 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

i used to have a chinese pug
anonymous

LOL!!! I Live in Florida!!! That's kinda funny. and ironic
anonymous
  • anonymous
haha yeah!
anonymous
  • anonymous
But seriously it's ACTUALLY called Florida Virtual School (FLVS)
anonymous
  • anonymous
mines called Ohio Virtual Academy (OHVA) from k12
anonymous
  • anonymous
These people come up with such non-creative names don't they
anonymous
  • anonymous
hahaha yes they do
anonymous

You know something. I've been doing Physics while helping you. I got bored
anonymous
  • anonymous
That's what I do when I get bored with school. I go on here and see if I can help anyone
anonymous
  • 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
  • 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
  • anonymous
right now its the end of the 1st semester. the 2nd semester starts on the 18th
anonymous
  • 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
  • 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
  • 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
  • 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
  • anonymous
yeah that isn't fair and i started homeschooling because the schools here are really bad
anonymous
  • anonymous
Oh that sucks
anonymous
  • 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
  • anonymous
okay :)
