y=mx+b slope intercept form where m is slope and b is y-intercept
if line increasing then slope would be `positive `
if line is decreasing then slope would be `negative`
slope = rise over run (count how many units its going up from the y-intercept and then how many units to the right )
b(y-intercept) is a point where line intersect at `y-axis`

so its a positive number right...this is just really confusing for me

- Nnesha

right slope would be positive bec line is increasing

- Taylor0402

i just cant tell if the line is increasing or decreasing

- Nnesha

heck your options are sure they are correct ?

- Nnesha

check ** sorry not that word

- Taylor0402

yes that is what they gave me

- Nnesha

then graph doesn't go with that options

- Taylor0402

i just can never tell hat way the slope is going how do i know it is going up or down...and after i figure that out i newere know which answer it is

- Taylor0402

if you had to pick the best answer what would it be

- Nnesha

alright
|dw:1444308980484:dw|
if the line coming from 2nd quadrant to 4th then the line is decreasing

- Nnesha

|dw:1444309061792:dw|
if the line is coming from 3rd quadrant to 1st then line increasing

- Taylor0402

oh ok got it

- Taylor0402

so the number has to be a negative

- Taylor0402

so it would be either a or b

- Nnesha

hmm why ?

- Nnesha

so is the line increasing or decreasing in ur graph ?

- Taylor0402

it is decreasing from my graph and as you said towards the top that decreasing is negative

- Nnesha

reread what i said :=)

- Taylor0402

now im confused :(

- Nnesha

|dw:1444309368772:dw|if the line coming from 2nd quadrant to 4th then the line is decreasing

- Nnesha

|dw:1444309392229:dw|if the line is coming from 3rd quadrant to 1st then line increasing

- Taylor0402

yes so the number would be a negitive right? =)

- anonymous

y = 1/6+0

- Nnesha

|dw:1444309473751:dw|
line is increasing or decreasing ?

- Taylor0402

OMG i am so sorry i put the wrong picture up and i didnt even notice it is this one

- Nnesha

see i told you

- Nnesha

\(\color{blue}{\text{Originally Posted by}}\) @Nnesha
then graph doesn't go with that options

- Taylor0402

that was from my last question...i am so sorry

- Nnesha

it's okay.

- Taylor0402

i will get the other one for you right now...ugh i feel so stupid :(

- Taylor0402

there it is...now i know this is the right one

- Nnesha

|dw:1444309675527:dw|
aw then yes line is decreasing slope would be negative

- Nnesha

now find y-intercept
y-intercept is a point where line intersect at y-axis

- Taylor0402

ok thats what i thought...now I feel smart again :)

- Nnesha

hahah yes you are smart!

- Taylor0402

no i am really bad at math you are the smart one here...if you were not helping rn i would get this wrong

- Taylor0402

it would be -2 right

- Nnesha

hmm slope is rise over run
so how many units its going down from the yintercept

- Taylor0402

oops it would be -1/2

- Nnesha

|dw:1444309931152:dw|

- Taylor0402

oh so thats what rise over run is

- Taylor0402

would it be 2

- Nnesha

how is it 2 ? please explain
how many units its going down from y-intercept ??

- Taylor0402

-4 but thats not an answer

- Nnesha

|dw:1444310141486:dw|

- Nnesha

right rise = -4 but we also need run so what's run

- Nnesha

how many units it's going to the right side ?

- Taylor0402

ok i would say -2

- Nnesha

right side where x values are positive so rise =-4
and run =2
slope = rise over run
replace rise with -4 and run with 2
and then divide

- Nnesha

\[\rm slope =\frac{ rise }{ run }=\frac{ -4 }{ 2 }\]

- Taylor0402

so the answer is A.-2

- Nnesha

right :=)

- Taylor0402

OMG thank you sooooo much

- Nnesha

np

- Taylor0402

if you ever need help on a question ( any subject but math) i would be glad to help

- Taylor0402

i am going to close this question but i have one more i need that i cant get

- Taylor0402

i will tag you in it

- Nnesha

alright and yes sure i will tag u when i need help thanks ! :=)
