I need help with these questions it's too hard to fit the problem and question together ​

Mathematics

Alona [7]4 years ago

Step-by-step explanation:

I can give you the formulas and how to do it.

The formula for finding the slope is

y²-y¹ all over(divided by) x²-x¹.

You take the order pairs and you label them.

For example, the first one.

(4,2) 4 can be x¹ and 2 can be y¹

(7,6.5) 7 can be x² and 6.5 can be y²

So then you plug it in.

(6.5-2) all over/divided by (7-4)

That ends up being 4.5 over 3. Fraction form.

That is your slope.

Then you plug the slope into the point-slope formula which is

y-y¹=M(x-x¹).

You plug your slope in for M.

You pick either of the given points and plug it in for y¹ and x¹.

Then you solve.

If done right, your formula will end up matching the slope-intercept formula

y=Mx+b.

M is your slope.

b is your y-intercept.

Dont freak out when you start doing it with fractions. Just because it looks wierd, doesnt mean it's wrong.

Use this process for all four.

Hope this helps.

zubka84 [21]
<span>for that, what you need is a calculator... like say a TI(texas instruments) 83 or 83plus or higher, will do regressions, if you have an android device like a phone or tablet, you can also get an app from the play store "Andie's graph", is a TI calculator emulator, it works just like the calculator itself, you'd only need the ROM 

</span><span>that said, you can also use some online calculators for that.
</span>
<span>I could give you a direct link to one, but this site has issues with links, if you do a quick search in google for "keisan exponential regression calculator", it should be the first link, is from the Casio site.
</span>
<span>you could do regressions in a spreadsheet as well.... you could check online for an "addin" or "extension", if you use MS Excel, pretty sure there are some addins for regressions.
</span>
if I recall correctly, Excel does regressions natively, but the addins are just frontends, is all, just some added interfacing.

anyhow, if you have an Android device Andie Graph works peachy, I have an 83plus, 84, 86 in it, they all work just like my old TI83plus.

there's also an app in the play store called Graph89, is an emulator for a TI89, the same you need a tiny little file, and texas instruments provides them, have also, works peachy too.
