- Phebe

Yes i do

- Phebe

i think i know the answer for part A

- Hero

What do you think the answer is for A? Please show your work as well.

- Phebe

Well for A its following a pattern which is x*5=y

- Hero

So what does that mean in terms of finding the rate of change?

- Phebe

i thought that was the answer

- Hero

I was looking more for something like:
The rate of change is _________ because ___________.

- Phebe

ok so The rate of change is x*5=y becausethats the pattern its going by?

- Hero

You should probably go back to your notes and make sure you understand exactly what rate of change is. You're on the right track, however, what you have isn't exactly correct as stated.

- Phebe

I do know what the rte of change is
its A rate of change is a rate that describes how one quantity changes in relation to another quantity

- Hero

Okay, so in this case, you figured out that y = 5x, which is a great start. It shows that the relationship between x and y is linear. The next step would have been to divide both sides by x. Then you would have y/x = 5, since 5 is the slope. In this case the slope of a line is the rate of change.

- Phebe

so 5 is the slope?

- Hero

Basically, when you have a linear equation of the form y = mx + b, the "m", the slope of the line is the rate of change. The terms "slope" and "rate of change" are synonymous as they apply to linear relationships.

- Phebe

So i was right?

- Phebe

@Hero

- Hero

Basically, another way to approach answering the question is to use the slope formula. We can take any two points \((x_1, y_1)\), \((x_2, y_2)\) from a line of the form y = mx + b, and apply it to the slope formula:
\(m = \dfrac{y_2 - y_1}{x_2 - x_1}\)
which will give us the rate of change, \(m\).

- Phebe

okay so hold on let me do that

- Phebe

so y1 would be 10 and y2 would be 20
from the graph they have right?

- Hero

Yes, you can let \(y_1 = 10\) and \(y_2 = 20\) for this calculation.

THERE!?!?!?!?! LOL

- Hero

Looks great so far. What value do you get for m?

- Phebe

so the value i got
10/2

- Hero

The rate of change is best expressed in the simplest possible form. The fraction 10/2 is reduceable.

- Phebe

so i devide it by 2 right
so 5/1?

- Hero

Yes, the rate of change for the given table is 5/1 or just 5.

- Phebe

OMG SO 5 is the answer right?

- Hero

Yes, but the correct answer is best expressed clearly, completely, and correctly and in sentence form. So if you said: "The rate of change for the quantities given in the table for part a is 5.", then that would be a great way to express your answer.

- Phebe

this is what i put: PART A: rate of change is 5 because, i used the
formula m=y2-y-/x2-x1

- anonymous

rate of change is more or less the slope

- anonymous

Its nothing fancy, just find the slope of every single one of them

- anonymous

btw i have the exact same textbook lol

- Phebe

LOL foreal?

- anonymous

yea lol i missed the part where hero said about slope whoops sorry to interrupt

- Phebe

lol its okay n are you homeschooled? nvm ill pm you
cuz hero trying to help me

- Hero

I guess the point is to avoid saying things like "the answer is 5" and to try to be explanatory with the answers you give. The actual answer you give can be described in a more explanatory manner if you properly express everything that you did. You could start with your pattern for example, and then introduce the idea that for linear equations, the slope of the line represents the rate of change for quantities x and y and then end by stating the obvious: "The rate of change is 5". My recommendation to you is to try journaling as you study Algebra or any mathematics. If you take a journalistic approach, it will help you to become more descriptive with your answers and it may help you to develop a more intuitive thinking process. Nothing fancy.

- Phebe

Yea im like a journalist but only in english class lol
Thanks for everything!!!! @Hero

- Hero

yw

- Phebe

:D !!!!!!!!!!!!!!!!!!

- Phebe

@Hero can you help me with part B

- Phebe

isnt it like the same as part A?

- Hero

Actually, I have to go. There are plenty other users available to help hopefully. Good night and good luck.

- Phebe

WELL GOODNIGHT!!! LOL

- Phebe

@whatdoesthismean
Help me then lol
if you want

- anonymous

Uh sure

- anonymous

So basically just like find the slopes like we said

- Phebe

thanks!!

- anonymous

B is very easy to find the slopes

- Phebe

so for B do i just solve tyhe equation?

- anonymous

Use the for y=mx+b

- anonymous

formula*
|dw:1436587663311:dw|

- Phebe

isnt that the answer? lol

- anonymous

well yeah, but you never answered so i thought i might as well work it out.

- anonymous

And btw its not the answer, its the equation

- Phebe

WELL THANK YOU!!!!!!

- anonymous

y=mx+b where m is the slope. SO what would m be

- Phebe

i solve the equation to get B right?

- anonymous

no non nononononono

- Phebe

LOLZZ!!!

- anonymous

you're trying to find slope.
the equation is in the form y = mx+b where M is the SLOPE
SO in this case what would m be????

- anonymous

hello????

- Phebe

I'm here lol

- Phebe

Would it be a fraction?
