Question

Many people dont agree but..

Answer 1

Many people dont agree that iit doesnt matter form which poin to subtarct when usng slope formula li
(x1, y1) (x2, y2) they dont agree that
(y1-y2)/(x1-x2)=(y2-1)/(x2-x1) it amtter to subtract from same pooint

Answer 2

You can use any 2 points you want to use the slope formula

Answer 3

i always tell them it doesnt matter
they are taught that it matters but it is wrong. there are many wrong materials today and probably hese people were taught by them. But in good books it doesnt matter.

Answer 4

I think we are taught :
\[m =\frac{ (y2-y1) }{ (x2-x1) }\] at school. :p

Answer 5

they are actually equal , I will prove it

Answer 6

they are @@Nnesha

Answer 7

I'm not Nnesha,lol. @AlexandervonHumboldt2

Answer 8

no i tagged nensha

Answer 9

to come hre s i always have disputes about itwith her

Answer 10

why not just use the formula taught at school rather than getting all confused with cancelling.

Answer 11

(y1-y2)/(x1-x2)
= ( - ( -y1 + y2) ) / ( - ( -x1 + x2))
= (-( y2 - y1))/(-(x2 - x1)
= (-1/-1)* ( y2 - y1) / (x2 -x1)
=(y2-1)/(x2-x1)

Answer 12

yeah great i know thats and now it is proved

Answer 13

either formula is correct, since they are equal (since its a ratio, the order does not count)

Answer 14

of course

Answer 15

no they jut say it is matter @uri they tell thats using another formula is A WRONG WAY

Answer 16

waooo you should tag me first

Answer 17

is slope arbitrarily defined? Can we define it as change in x over change in y?

Answer 18

hmm see @Nnesha i was riight?

Answer 19

lol @uri

Answer 20

i think we could but it would make calculating more complicated

Answer 21

see what he said

Answer 22

hey!!!!

Answer 23

Don't make your life so complicated, @AlexandervonHumboldt2 lol

Answer 24

ok

Answer 25

i will come back and read this whole essay i gtg now

Answer 26

it is better to listen to me than dispute. i say only that is proved i dont tell my maybes

Answer 27

bye now

Answer 28

and my name is

Answer 29

hmmm

Answer 30

but formula is
yeah like perl said we can take out negative our in other case
and that's why its a loooooot work
some user already don't want to put effort in
so it reallyy toooo much for them to take out negative
you can use like you did on last question
- 3 - 4 and you did like this ---- > (3+4) did you explain them how its turn to 3+4
so if you use normal formula then we don't have to explain bnch of things
