  • Phebe
Yes i do
Phebe
  • Phebe
i think i know the answer for part A
Hero
  • Hero
What do you think the answer is for A? Please show your work as well.
Phebe
  • Phebe
Well for A its following a pattern which is x*5=y
Hero
  • Hero
So what does that mean in terms of finding the rate of change?
Phebe
  • Phebe
i thought that was the answer
Hero
  • Hero
I was looking more for something like: The rate of change is _________ because ___________.
Phebe
  • Phebe
ok so The rate of change is x*5=y becausethats the pattern its going by?
Hero
  • 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
  • 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
  • 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
  • Phebe
so 5 is the slope?
Hero
  • 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
  • Phebe
So i was right?
Phebe
  • Phebe
@Hero
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
  • Phebe
okay so hold on let me do that
Phebe
  • Phebe
so y1 would be 10 and y2 would be 20 from the graph they have right?
Hero
  • Hero
Yes, you can let \(y_1 = 10\) and \(y_2 = 20\) for this calculation.

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