I am looking for a website that does the following. (1) I enter a linear equation (e.g., y = 2x + 5) and the website graphs the correct line. Or (2) I enter the data points (ordered pairs such as (1,1), (2,2), (3,3), etc.) and the website graphs the correct line. Also, I'd like to be able to print the results. Finally, is there a way in Excel (or Word) to do something similar?
The gist of my problem is this. I have to graph several equations. And I'd want to submit the work so that it is neat (i.e., computer-generated or word-processed) and not hand-written. Any suggestions? I want it to look like the graphs of linear equations that you might see in a textbook, and not one that is written by hand. Like, for example, the two graphs shown at the very bottom of this page: [1]. Or this page: [2]. There must be something out there that does this. That makes this task easier. Any suggestions? Thank you. — Preceding unsigned comment added by 2602:252:D13:6D70:19F4:A168:19D0:22A1 ( talk) 04:26, 14 October 2015 (UTC)
OK. Thanks. I tried it in Excel. It seems to work OK. So, another question about the Excel process (Excel 2013, if it matters). How can I "format" the Cartesian Plane so that it always extends the "x" variable (horizontal line) from -10 to +10, and so that it always extends the "y" variable (vertical line) from -10 to +10? I explored the options, and I can see where I can control one number line, but not the other. The actual Cartesian Plane "boundaries" seem to change, depending on what the actual line looks like. I'd like to get a uniform plane of 10 by 10 for both axes. Is that possible? Thanks. — Preceding unsigned comment added by 2602:252:D13:6D70:9433:3444:F704:E383 ( talk) 17:36, 14 October 2015 (UTC)
In other words, I want the Cartesian Plane to look like this: [3], a "standardized" plane that always extends from -10 to +10 on both axes. And I want to draw the line on that standard template, wherever the line may happen to fall, within that grid. Thanks. 2602:252:D13:6D70:9433:3444:F704:E383 ( talk) 17:41, 14 October 2015 (UTC)

Assuming that we have a set, A, what is the minimum of the intersection of its subsets? Formally: Let be three numbers. Let A be a set of size n (|A|=n). Let P(A) denote the power-set of A. Let . What is the value of ?
--Edit-- I am not intersted in the the exact value, but only in the answer for the following question: Assuming also that n is determined first, and then m, k are determined as functions of n (so, I shall denote their corresfonding functions as respectievly, and I shall denote the desired value above as ). My question is: Are there some constant c < 0.5, and functions and polynomial such that and (peforming f for n times keeps the result < cn)

Thanks for the extra and helpful comments, guys. Gurumaister ( talk) 15:28, 15 October 2015 (UTC)
After some efforts I succeded to rephrase my question: Given v, k. Is there , and a abelian difference set, D ? 212.199.149.142 ( talk) 08:30, 16 October 2015 (UTC)
