Question

what is the slope intercept form of f=4(s-65)+10

Answer 1

huh?

Answer 2

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

Answer 3

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

Answer 4

what do f and s stand for?

Answer 5

f=find & s=speed but i have tu put the equation in slope intercept form

Answer 6

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.

Answer 7

Hmm, the teacher may not agree with that, even though you are correct.

Answer 8

@polpak & @michael.3245 do u guys have an answer

Answer 9

Well, slope intercept form is y=mx+b

Answer 10

What is the number you are trying to find? F or S?

Answer 11

s=78 , we have to find f

Answer 12

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!

Answer 13

From this we can see that the slope of this line is 4, and the y intercept is (0, -250)

Answer 14

additionally, it is easy to plug in 78 for s and find f.

Answer 15

f=4(78)-250
f=312-250
f=62

Answer 16

thank u but i have another problem

Answer 17

ok, go!

Answer 18

f=10(s-55)+40 ... s=67 & its the same way

Answer 19

Well, lets do this one together.

Answer 20

can you distribute out the 10?

Answer 21

if s=67 then 10*67 is 670 & 10*55 is 550 .. am i rite?

Answer 22

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

Answer 23

i dont get it

Answer 24

f=10(s-55)+40
so we now have
f=10s-550 + 40

Answer 25

we want to simplify it first, then plug in s.

Answer 26

ohh okay! so with that wat do we do next

Answer 27

after you can't simplify it any more, you are in slope intercept form, and you can plug in s.

Answer 28

Continue the simplification. We have this:
f=10(s-55)+40
f=10s-550 + 40
You know what to simplify next, right?

Answer 29

actually no! i dont no math at all

Answer 30

*know

Answer 31

Well, you need to learn, and I'm afraid just giving you the answer won't help.

Answer 32

So, lets proceed.

Answer 33

If I have -550 + 40, how do you simpiify that?

Answer 34

will it be -510

Answer 35

Yep!

Answer 36

so the answer is f=10s-510 ... am i rite ?

Answer 37

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.

Answer 38

Now what?

Answer 39

one min. i need tu see wat is next

Answer 40

ok now! it says that f = two equations at one time

Answer 41

erm, we can still plug in 67 on that other problem.

Answer 42

no! this is a whole different problem

Answer 43

but that is easy stuff, give me the system of equations real quick, then ill go to bed.

Answer 44

lets do the system of equations real quick
