Regression & Graphing

[Ellen Kennedy]

****o Every1;

Thanks to all of you that posted a response to my guestions. I haven't gotten anywhere because I don't understand any of it. This is why I'm asking for help to solve all 6 parts to the Question that I posted on last night. SO, can anyone help me understand this for future references. I appreciate all that respond, I nessed help like two weeks ago. I have been trying to understand but, I can't figure this problem out at all.

I do have a teacher but, I can't follow her teaching because she goes to fast. I got behind in my course because of illness and death in my family. I'm a Criminal Justice Student and I'm taking Math140-1103A-12. We're studing Linear Equations and Regressions and Graphing is part of this course. I'm taking an online course at Colorado Technical University. I have until 11:59 tonight to post this assignment. So, if anyone can help me I really would appreciate it.



Thanks,
Ellen

having problems myself

I actually need help as well I am not sure I am understanding the following problem can anyone help me. and its due tomorrow .

Scenario: Regression equations are created by modeling data,
such as the following:

Profit = (Cost Per Item × Number of Items) – Constant
Charges​

In this equation, constant charges may be rent, salaries, or other fixed
costs. This includes anything that you have to pay for periodically as a
business owner. This value is negative because this cost must be paid each
period and must be paid whether you make a sale or not.

Your company may wish to release a new e-reader device. Based on data
collected from various sources, your company has come up with the following
regression equation for the profit of the new e-reader:


Profit = $0.15 × number of e-readers sold – $28

Or, assuming x = the number of e-readers sold, this would be the
same regression equation:

Profit = 0.15x – 28


In this case, the values are given in thousands (i.e., the
cost of making an individual e-reader will be $150 [0.15 × 1,000], with $28,000
[28 * 1,000] in constant charges).
Answer the following questions based on the given regression equation:

1. Using the graphing program that you downloaded, graph the profit equation.
   Discuss the meaning of the x- and y-axis values on the graph. (Hint: Be sure to
   label the axis)
2. Based on the results of the graph and the profit equation provided, discuss
   the relationship between profits and number of e-readers produced. (Hint:
   Consider the slope and y-intercept.)
3. If the company does not sell a single e-reader, how much is lost ?
   Mathematically, what is this value called in the equation?
4. If the company sells 5,000 e-readers, how much will the company make (or
   lose)?
5. If profit must equal 100 thousand, how many e-readers will your company need
   to sell? (Round up to the nearest e-reader.)
6. If your company is hoping to break even, how many e-readers will need to be
   sold to accomplish this? (Round up to the nearest e-reader.)Please submit your
   assignment.

Urgent i need help and it's due tonight!!!

Yes, I can't access the archive chat for the same problem. It is due by 10 pm tonight and I also have to graph it.
