I know this question hasn't anything to do with math, but I would appreciate help. (Please forgive my poor english.)

I'm having an economic class and I'm really having troubles trying to differentiate (make a distinction between) a line with upward movement and rightward shift. For example, look the lines at this page:

. . .http://www.oswego.edu/~economic/eco350/c2_6.gif

Did the line named D experience an upward movement or a rightward shift?

Also, if any of you know something about economics, could you tell me why, in the supply curve, when the price increases the curve experiences an upward movement and there is a decrease in quantity supplied?

again, sorry for posting this which probabbly hasn't anything to do with math
please don't delete this post, at least until i can read the answers
bye
 
One clue for differentiating vertical movement from horizontal movement is the Domain and the Range. What were they before? What are they now? This is one reason those terms were introduced, so you could use them later in life.

Did the Domain change and the Range stay the same? You may wish to consider this horizontal movement.

You can figure out the other possibilities.
 
tkhunny, thanks
could you please explain it in a eassier way? sorry, i'm not very smart., if you could provide me some examples, i'd really appreciate it
thanks

What the tutor provided was fairly "easy" -- assuming the reader is familiar with the concepts of domain and range, and how they relate to graphing.

Unfortunately, it is pretty much impossible to try to re-create classroom instruction within this environment. So, to obtain the lessons you have requested (explanations and "some examples"), please consult with your instructor, your text, your tutoring centre, or with online resources. Or please conference with your academic counsellor regarding obtaining the missing prerequisite material.

My best wishes to you.

how are u doing stapel, yeah i'm familiar with domain and range, domain is placed in the x axis, while range is placed in the y axis

so when the domain changes and the range stays the same we get a line like this one _________________________________


but please take a look at the lines of this page

what are they? Did the line named D changed in a vertical or horizontal way???? i don't get it! help!
thankss[/url]
 
I'm only in 11th grade taking pre-cal right now but after looking at that graph you can tell that as the quantity of labor demanded increased the wage rate decreases so it depends what you are trying to figure out.. i don't understand exactly what you're asking but i hope this helps a little

I think you are trying to make a distinction where there is none. The demand curve shifted and you need to know the effects of that shift. For example, after the shift, did the quantity of labor demanded for a given wage rate increase or decrease?

If your textbook has a definition of what is an upward movement versus a rightward shift, please show us the exact wording. And if you have question that asks you to distinguish between those two, please show us the exact wording of that also.

As long as you are thinking like that, you cannot succeed in this course.

I suggest you change either your attitude or your class schedule.

No. When the domain changes but the range stays the same, one gets whatever curve one originally had (not at all necessarily an horizontal line), but shifted to wherever the new domain is.

Look up "horizontal" and "vertical", and then look at the graph again. Consider the direction in which the first line would have to be moved, in order to overlay the second line.

Wass up people, thank you for your time and answers

sadly my book doesn't have any definition of those terms

stapel, so When the domain changes but the range stays the same there is an horizontal change, and i suppose there is a vertical change when domain stays the same but the range changes??
thanks
 
Under the assumption of a negative-sloped demand curve, right and up are not different, excepting some Domain and Range issues. It is possible some arrangements will be renderred impossible.

In the attached link, one cannot get from D to D' using ONLY "up" or "right" in their traditional axiomatic interpretation. It's a North-East shift - a little of both.

Having said that, I'd have to agree strongly with JakeD and wonder what the question actually wants.
