my guess would be that its because y is equal to whatever 12(x) is going to be.
but that seems too easy
i know. How about y = 4x+1

the asnwer is no
i am probably in over my head.. sorry
here's something you can remember... if y and x are in one line...then it's a direct variation if either y or x is in the denominator...then inverse variation
\[y = kx \leftarrow \; \text{direct variation}\] \[y = \frac kx \leftarrow \; \text{inverse variation}\]
ok so how does that apply to my first problem
y = 12x <--in the for y = kx <--can you see that?
in the form*
oh ok so how does it arie directly with x.. Im sorry im just not seeing the picture
varie* My teacher isnt that good
look at what i said above about y = kx
yeah I know but what does K mean how the flutter does it varie with anything?
k is a constant
it is called the proportionality constant
it means its value doesnt matter because it is constant..in other words...always stays the same
ok now I get why 12 is there.. So now explain the rest please?
in your terms... k is the constant variation
first tell me... do you agree that y = 12x is in the form y = kx?
is y = k? which is 12? and how does that varie to x?
Yeah I get that
what do you see as difference between \[\huge y = kx\] and \[\huge y = 12x\]
yeah I see that
spot the difference
not the similarity
yeah
what do you mean yeah?
I spot the difference
what's the difference??
12 instead of K
RIGHT! that's why 12 is the constant variation
because k is the constant variation..and k = 12
ohhh K= Constant Variationnnnnn
yes!
lmfao face to palm**
ok so what about this one y = 4x + 1
the answer to that one was "NOT direct variation" right?
yes
that's because of the 1 y = 4x + 1 is not in the form y = kx because of that 1
what about y - 6x = 0
;)
simplify it first
solve for y first
can you do it?
I dont wnana get confused
add 6x to both sides
add 6 to 0?
6x..not 6
yeah
y-=6x?
im a idiot
y-?
lmfao it was negative
OH NVM
alright so the answer is 6!
yes
what about y _ 3 = -3x
-
what do you think?
add 3 to both sides
y= x?
you can't combine 3 and 3x
is that a constant variation?
no..im just talking about algebra
Ah forget about that one can you help me with proportions? i'll open up a new question
i have to go soon
awe ur like the best lol
call saifoo or amistre
eh Saifoo is a fool now he used to be cool
amistre doesnt help me anymore
