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

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

    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.

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

    Well, slope intercept form is y=mx+b

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

    s=78 , we have to find f

    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!

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

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

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

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

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

    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

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

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

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

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

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

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

  37. 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.
