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

just say, hey pika, you are full of shit

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

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

college linear 1 is easy

its when you get to the machine learning stuff when its gets really confusing

linear algebra was mostly proofs for me

computation was fine

linear is all just matrix reduction to echelon form

if you know that you know that class

i'll worry about that next year

Or if it was my class, all diagonalization

for the last part of the course

and half of lin alg 2

diagonalization is row reduction
