Sorry... I'm doing linear algebra at the moment. This simple stuff is fun compared to that! @_@



Random game thought :
Why is Bionic Commando Rearmed 2 getting so much hate? We finally get a real game and they're not even satisfied... I'm starting to hate the gaming community so f****** much...

Scratch that, I'm sure it was free when I used it....5 years ago. I'll find you a new one




I though I learned that in Algebra 1....

Problem already solved, though.

Whoo! I'm also doing linear algebra. And we both live in Québec! And we both speak french! We might even be in the same class O.o  :P



OK, Soriku, this one should do, try it

Oh, the excitement! Je viens de l'Estrie... Ça te dit de quoi? xD

Hmm, that program looks really complicated :P Are you sure it does things like parallel lines and perpendicular lines?

Ehm, it does more than that...I mean, the Windows Calculator does sine and cosine, that doesn't mean it can't do sums and multiplications

I never used that program, to be honest, I used Graphmatica (which I swear I have a free version), you can plot either by equation or by two points, so I guess this one should too




Soriku said:
WTF this program makes no sense.

I'm trying to plot y = 5x + 3 but I have to input this in some function calculator or something?

Graph -> New Function -> Type it without the Y, just as 5x+3, and it's graphed. I'm trying to figure out if it graphs based on coordinates too




Rise over Run. Y=rise X= run



Soriku said:

OK so I start out at 3. How many places do I go up and left? There's no points, only a line...

Plus do you know how to graph parallel/perpendicular lines?

Perpendicular functions have a slope (the number that's multiplying the x) that multiplied by the other fuction's slope is equal to -1

Therefore, the perpendicular equation would be y=-1x/5 + b, with b depending on which point you want it to pass

 

Paralell lines have the same slope, but different independent term, again, it depends for which point it should pass

 

I don't know what's your trouble, find the equation you need and graph it. Or you can't find the equation you need?
