Best ResponseYou've already chosen the best response.5Do you know what a rate of change is?

Phebe

Best ResponseYou've already chosen the best response.0i think i know the answer for part A

Hero

Best ResponseYou've already chosen the best response.5What do you think the answer is for A? Please show your work as well.

Phebe

Best ResponseYou've already chosen the best response.0Well for A its following a pattern which is x*5=y

Hero

Best ResponseYou've already chosen the best response.5So what does that mean in terms of finding the rate of change?

Phebe

Best ResponseYou've already chosen the best response.0i thought that was the answer

Best ResponseYou've already chosen the best response.5I was looking more for something like: The rate of change is _________ because ___________.

Phebe

Best ResponseYou've already chosen the best response.0ok so The rate of change is x*5=y becausethats the pattern its going by?

Best ResponseYou've already chosen the best response.5You 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.

Best ResponseYou've already chosen the best response.0I 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

Best ResponseYou've already chosen the best response.5Okay, 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.

Best ResponseYou've already chosen the best response.5Basically, 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.

Best ResponseYou've already chosen the best response.5Basically, 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, \(m\).

Best ResponseYou've already chosen the best response.0okay so hold on let me do that

Phebe

Best ResponseYou've already chosen the best response.0so y1 would be 10 and y2 would be 20 from the graph they have right?

Hero
 one year ago
Best ResponseYou've already chosen the best response.5Yes, you can let \(y_1 = 10\) and \(y_2 = 20\) for this calculation.

Best ResponseYou've already chosen the best response.5Looks great so far. What value do you get for m?

Hero

Best ResponseYou've already chosen the best response.5The rate of change is best expressed in the simplest possible form. The fraction 10/2 is reduceable.

Phebe

Best ResponseYou've already chosen the best response.0so i devide it by 2 right so 5/1?

Hero
 one year ago
Best ResponseYou've already chosen the best response.5Yes, the rate of change for the given table is 5/1 or just 5.

Phebe

Best ResponseYou've already chosen the best response.0OMG SO 5 is the answer right?

Hero
 one year ago
Best ResponseYou've already chosen the best response.5Yes, 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

Best ResponseYou've already chosen the best response.0this is what i put: PART A: rate of change is 5 because, i used the formula m=y2y/x2x1

Best ResponseYou've already chosen the best response.0rate of change is more or less the slope

anonymous

Best ResponseYou've already chosen the best response.0Its nothing fancy, just find the slope of every single one of them

anonymous

Best ResponseYou've already chosen the best response.0btw i have the exact same textbook lol

anonymous

Best ResponseYou've already chosen the best response.0yea lol i missed the part where hero said about slope whoops sorry to interrupt

Phebe

Best ResponseYou've already chosen the best response.0lol its okay n are you homeschooled? nvm ill pm you cuz hero trying to help me

Best ResponseYou've already chosen the best response.5I 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.

Best ResponseYou've already chosen the best response.0Yea im like a journalist but only in english class lol Thanks for everything!!!! @Hero

Best ResponseYou've already chosen the best response.0@Hero can you help me with part B

Phebe

Best ResponseYou've already chosen the best response.0isnt it like the same as part A?

Hero

Best ResponseYou've already chosen the best response.5Actually, I have to go. There are plenty other users available to help hopefully. Good night and good luck.

Best ResponseYou've already chosen the best response.0@whatdoesthismean Help me then lol if you want

anonymous

Best ResponseYou've already chosen the best response.0So basically just like find the slopes like we said

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0B is very easy to find the slopes

Phebe
 one year ago
Best ResponseYou've already chosen the best response.0so for B do i just solve tyhe equation?

anonymous

Best ResponseYou've already chosen the best response.0formula* dw:1436587663311:dw

Phebe

Best ResponseYou've already chosen the best response.0isnt that the answer? lol

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0well yeah, but you never answered so i thought i might as well work it out.

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0And btw its not the answer, its the equation

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0y=mx+b where m is the slope. SO what would m be

Phebe
 one year ago
Best ResponseYou've already chosen the best response.0i solve the equation to get B right?

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0you'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????
