Question

help me ? :)

Answer 1

@tejasvir

Answer 2

i think it is decreases the steepness

Answer 3

let us not say I think, and let us approach this mathematically as well as analytically

Answer 4

x - 2y = 4
let us try converting this standard form into slope-intercept form
that is Ax+By = C into y = mx + b

Answer 5

meaning solve for y

Answer 6

idk how :( I think the ''dumb blonde'' thing goes really well with me lol

Answer 7

yeah? most blondes I know are smart

Answer 8

do you know how to solve for y?

Answer 9

nooo O';

Answer 10

its an inverse relationship.. so it probably is decreases

Answer 11

if you solve for y.

Answer 12

yeah i got C too :3

Answer 13

Ax + By = C

REMEMBER that A, B and C are coefficients (do you know what coefficients are)

isolate y by first subtracting Ax to both sides

Ax - Ax + By = C - Ax
becomes
By = C - Ax

then divide both sides by B
(By)/B = (C - Ax)/B
becomes
y = (C - Ax)/B or y = -Ax/B + C/B
where A/B is your slope and that determines whether it is increasing, decreasing, zero or undefined.

Answer 14

so is it D or C =.=

Answer 15

let me give you a more concrete example

in the standard form
2x - 5y = 10 identify whether it is increasing or decreasing

with the standard form Ax + By = C
the coefficients are:
A = 2
B = -5
C = 10

like I said earlier let us solve for y to convert the equation into SLOPE-INTERCEPT form

2x - 5y = 10
subtract 2x on both sides
2x - 2x - 5y = 10 - 2x
becomes
-5y = 10 - 2x

then divide -5 on both sides
-5y/-5 = (10-2x)/-5
becomes
y = 10/-5 -2x/-5

simplifies into:
y = -2 + 2x/5 or in the format of y = mx+b
y = 2x/5 - 2

slope is the coefficient with x, that is the m value
= 2/5

it is positive so it is INCREASING

Answer 16

OMFG THANKS SM SO ITS D?!

Answer 17

I don't know
you have to solve your own problem, I just gave you a different example with the SAME concept

Answer 18

wait if you solve for y
you get (c-ax)/b = y
isnt that an inverse relationship?

Answer 19

do you know what an inverse relationship is @tejasvir ?

Answer 20

yea... as one increases the other decreases..

Answer 21

like y = 1/x --> if you increase the x the y decreases if you decrease the x the y increases

Answer 22

wrongggggggggg omfg it was B

Answer 23

so what increased in what decreased in that problem?

Answer 24

so if you increase the b... the y decreases and if you decrease the b the y increases

Answer 25

so answer b would make sense

Answer 26

lol yeah i submitted and they said it was B

Answer 27

idk youre probably right @nincompoop

Answer 28

i was thinking of it in a different way. i guess that was wrong

Answer 29

@tejasvir you are looking at this problem incorrectly

Answer 30

the way to answer this problem is to solve for y, that is converting the standard form of linear equation into slope-intercept form

Answer 31

okay. sorry.
