general

that is about the limit of my knowledge

invert the equation to use the vertical asymptote i guess

I don't even know what an asymptote is Kapap

Okay, so we know b-2c = 0 since the system goes asymptotically

so b = 2c

thats a start

ok

the inverse is (a-yb)/(cy-1) = x

then you can break the equation up into a/b+cx and x/b+cx

that might help

hmm

so cy-1=0

at y=2

c = 1/2

then b=1

can solve for a by looking where x intercept is

it's at 2

a/b =2

so I suppose a= -2

oh wow that was simpler than I was making it out to be

should just be 2 if I am not being stupid

x-intercept is at 2

so a = -2

since you have a/b+cx

=2

so a/b = 2 and b = 1

so a=2

wait

that gives a straight line

the x-intercept is at 2, so a+x=0 when x=2

so a= -2 right?

okay You are right

I think

i mean i have an answer key and it says a=-2

oh

ffs

why did you let me argue with you

lmao

and have not had to do a question like this ever

also it's a four point question and one of the points is just "tried to use asymptotes" and the other three are correct answers

ib grading is weird

I fucking pulled out pen and paper for this shit

lol

oh my bad pika

no worries

lol

I enjoy math

would not be in what is essentially 50% a math program if not

wait hold on leg

how do you get that inverse

Set x as y

then solve for y

so you get (a + y)/ (b+cy) = x

then just multiply over, factor out common ys, and write that in terms of y

yeah got it

leg switched x and y and it was confusing

because that is what you do

well, not switched

anyway i got it

wait no somehow i got an extra -1 in both numerator and denominator

if I didn't already know the answer i wouldn't take it out

should just be y at the end on the right

i mixed 2 steps

i did:

x(b+cy) = a+y

y-cxy = bx-a

y(1-cx) = bx-a

y= (bx-a) / (1-cx)

thats what I did

then 1-2c = 0

oh i'm fucking dumb as shit

god dammit i can't do fuckin algebra

as my teacher says, "calculus is easy, algebra is hard"

this was more relevant when i was actually in calculus but w/e

linear algebra is confusing

linear algebra sounds scary
