huh?

Which variable is for the vertical axis, and which one is for the horizontal axis?

i dont know actually! its a paragraph you have to read

what do f and s stand for?
anonymous
  • anonymous
f=find & s=speed but i have tu put the equation in slope intercept form
anonymous
  • anonymous
Well, it doesn't matter much. Solving one for slope intercept will be correct, it just depends on how you wanted to graph it. But the one you solve for will determine that.
anonymous
  • anonymous
Hmm, the teacher may not agree with that, even though you are correct.

@polpak & @michael.3245 do u guys have an answer
anonymous
  • anonymous
Well, slope intercept form is y=mx+b
anonymous
  • anonymous
What is the number you are trying to find? F or S?
anonymous
  • anonymous
s=78 , we have to find f
anonymous
  • anonymous
Ah, thank you! So, we need to solve for F. f=4(s-65)+10 here, we use the distributive property to get rid of the parenthesis. f=4s-260+10 and simplifying gets us f=4s-250 wala! We are now in slope intercept form!
anonymous
  • anonymous
From this we can see that the slope of this line is 4, and the y intercept is (0, -250)
anonymous
  • anonymous
additionally, it is easy to plug in 78 for s and find f.
anonymous
  • anonymous
f=4(78)-250 f=312-250 f=62
anonymous
  • anonymous
thank u but i have another problem
anonymous
  • anonymous
ok, go!
anonymous
  • anonymous
f=10(s-55)+40 ... s=67 & its the same way
anonymous
  • anonymous
Well, lets do this one together.
anonymous
  • anonymous
can you distribute out the 10?
anonymous
  • anonymous
if s=67 then 10*67 is 670 & 10*55 is 550 .. am i rite?
anonymous
  • anonymous
well, you want to get slope intercept first, so we don't have to deal with s=67 yet. 10(s-55) simpilifies to 10s-550
anonymous
  • anonymous
i dont get it
anonymous
  • anonymous
f=10(s-55)+40 so we now have f=10s-550 + 40
anonymous
  • anonymous
we want to simplify it first, then plug in s.
anonymous
  • anonymous
ohh okay! so with that wat do we do next
anonymous
  • anonymous
after you can't simplify it any more, you are in slope intercept form, and you can plug in s.
anonymous
  • anonymous
Continue the simplification. We have this: f=10(s-55)+40 f=10s-550 + 40 You know what to simplify next, right?
anonymous
  • anonymous
actually no! i dont no math at all
anonymous
  • anonymous
*know
anonymous
  • anonymous
Well, you need to learn, and I'm afraid just giving you the answer won't help.
anonymous
  • anonymous
So, lets proceed.
anonymous
  • anonymous
If I have -550 + 40, how do you simpiify that?
anonymous
  • anonymous
will it be -510
anonymous
  • anonymous
Yep!
anonymous
  • anonymous
so the answer is f=10s-510 ... am i rite ?
anonymous
  • anonymous
Yes! You are getting it now! f=10(s-55)+40 f=10s-550 + 40 f=10s-510 Now, we are completely simplified. It fits the form y=mx+b, or in this case f=ms+b, so we are in slope-intercept form.
anonymous
  • anonymous
Now what?
anonymous
  • anonymous
one min. i need tu see wat is next
anonymous
  • anonymous
ok now! it says that f = two equations at one time
anonymous
  • anonymous
erm, we can still plug in 67 on that other problem.
anonymous
  • anonymous
no! this is a whole different problem
anonymous
  • anonymous
but that is easy stuff, give me the system of equations real quick, then ill go to bed.
anonymous
  • anonymous
lets do the system of equations real quick
