I accidentally out-of-the-boxed linear equations

[Axolotl2]

ax+by = c --> y = (-a/b)x + c/b

y-y1 = m(x-x1) --> y = m*x - m*x1  + y1

how the forget did they not teach this in the geometry book

Because it was implied, seeing how they do equal eachother, and that any rearrangement of the variables will result in the same answer.

Such as the Ideal gas formula from Chem 1 last year.

PV=nRT
or
V=(nRT)/P
or
P=(nRT)/V
or
T=(PV)/(nR)
or
PV=(m/w)RT

How about the combination of the Kinematic equations?  There are so many solvations, rearrangements, and combinations that I'm not even gunna try to type them out.

Later on in school, it'll/it is implied that you should be able to solve for any specified variable, given a formula to use, and that any rearrangement of the formula will get the same answer.

I think I am one of the few people in my high school who can do this in 9th grade.

how do i not know exactly what a linear equation is by name

[_Rave_]

didnt you forget that up?

isn't that

It makes a line, when graphed. E.g., x-2 or 43t+14.

well only a straight line, no exponents other than +/- 1 or 0

[Wynd_Fox]

Well, straight line is redundant, isn't it? And it would have to have one of those exponents to make a (straight) line, wouldn't it?

[Megaguy2]

I have no idea what is going on in this thread.

oh yeah

well a positive or negative 1 or zero, yes

[Trinick]

And it would have to have one of those exponents to make a (straight) line, wouldn't it?

What? An exponentiated variable would make a curved line, like a parabola or hyperbola, or just a graph of exponential decay or growth.

oops meant to edit that into ^

[fred da kiko]

my line is -0 meters long.

[Trinick]

my line is -0 meters long.

Then it's a point, not a line.
