Equation generator?

There HAS to be something online to do this but I'll be darned if I can't find it!

You CAN do it in Excel tho. It's not that hard. I tried it just to make sure. If you are interested send me a message and I will tell you how to do it. It will (or can be made to easily enough) display the equation for any two points you choose.

Sorry, but this is all I can come up with for you.

Would you be interested in doing your own programming?

You can download a freeware program of the basic

language, called "Microsoft QuickBASIC 4.5" from :-

Basic is a very easy language to learn and you don't have

to learn all of it to use it. I use it all the time, mainly

because I haven't got around to learning any other

language yet, and I probably won't.

It's so easy to set up "millions" of short programs to do

interesting things that would take ages on a calculator.

Unless you have a programmable calculator, that is, and

that would be ideal for this sort of problem.

How to go about it -

Assume the equation you want is : y = mx + b.

Let your 2 points be (x1, y1) and (x2, y2).

Then you would just program in :

m = (y2 - y1) / (x2 - x1)

and

b = y1 - m * x1

When you input the 2 points, m and b then pop up

automatically. If you use a computer programming

language, you can display things exactly as you want,

and you could graph it at the same time, in colour!

Get to know some computer nerds to help you.

If you have such interests at your age, you'll soon be

old enough to realise that you wished you had

learned a computer language long ago. It doesn't

have to be BASIC; whatever is going these days.

Here is what the program would look like in BASIC :

CLS (this clears the screen)

INPUT x1, y1, x2, y2

m = (y2 - y1) / (x2 - x1)

b = y1 - m * x1

PRINT "y ="; m; "x +"; b

If you input 3,5,1,8 (meaning points (3, 5) and (1, 8),

the output will be : y = -1.5 x + 9.5
