@Phebe, what are your thoughts regarding this problem?
Do you know what a rate of change is?

Yes i do
i think i know the answer for part A
What do you think the answer is for A? Please show your work as well.
Well for A its following a pattern which is x*5=y
So what does that mean in terms of finding the rate of change?
i thought that was the answer
I was looking more for something like: The rate of change is _________ because ___________.
ok so The rate of change is x*5=y becausethats the pattern its going by?
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.
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
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.
so 5 is the slope?
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.
So i was right?
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, \(m\).
okay so hold on let me do that
so y1 would be 10 and y2 would be 20 from the graph they have right?
Yes, you can let \(y_1 = 10\) and \(y_2 = 20\) for this calculation.
|dw:1436586160912:dw| THERE!?!?!?!?! LOL
Looks great so far. What value do you get for m?
so the value i got 10/2
The rate of change is best expressed in the simplest possible form. The fraction 10/2 is reduceable.
so i devide it by 2 right so 5/1?
Yes, the rate of change for the given table is 5/1 or just 5.
OMG SO 5 is the answer right?
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.
this is what i put: PART A: rate of change is 5 because, i used the formula m=y2-y-/x2-x1
rate of change is more or less the slope
Its nothing fancy, just find the slope of every single one of them
btw i have the exact same textbook lol
LOL foreal?
yea lol i missed the part where hero said about slope whoops sorry to interrupt
lol its okay n are you homeschooled? nvm ill pm you cuz hero trying to help me
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.
Yea im like a journalist but only in english class lol Thanks for everything!!!! @Hero
yw
:D !!!!!!!!!!!!!!!!!!
@Hero can you help me with part B
isnt it like the same as part A?
Actually, I have to go. There are plenty other users available to help hopefully. Good night and good luck.
WELL GOODNIGHT!!! LOL
@whatdoesthismean Help me then lol if you want
Uh sure
So basically just like find the slopes like we said
thanks!!
B is very easy to find the slopes
so for B do i just solve tyhe equation?
Use the for y=mx+b
formula* |dw:1436587663311:dw|
isnt that the answer? lol
well yeah, but you never answered so i thought i might as well work it out.
And btw its not the answer, its the equation
WELL THANK YOU!!!!!!
y=mx+b where m is the slope. SO what would m be
i solve the equation to get B right?
no non nononononono
LOLZZ!!!
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????
hello????
I'm here lol
Would it be a fraction?
