@THEUSER822

OpenStudy (anonymous):

@Nnesha plz help me

Nnesha (nnesha):

first look at the y-axis what is a point where line touch y -axis

OpenStudy (anonymous):

wait is my answer correct for quesion 1

Nnesha (nnesha):

nope :(

OpenStudy (anonymous):

man foreal lol

Nnesha (nnesha):

yesh :(

Nnesha (nnesha):

thats y i'm asking where in the y-axis line touches

OpenStudy (anonymous):

qait is it a

Nnesha (nnesha):

your y-intercept is where line touch y - axis

OpenStudy (anonymous):

isnt that a positive 4 @Nnesha

OpenStudy (ffrocks3):

It's D Because you start at y = 1 and you go down 3 over 1 because m = 3x

OpenStudy (ffrocks3):

Hope That Helps !

OpenStudy (anonymous):

so it is d

OpenStudy (ffrocks3):

Yes :)

OpenStudy (anonymous):

next one

OpenStudy (ffrocks3):

what next one?

Nnesha (nnesha):

here is y -intercept always first you have to look at y-intercept

Nnesha (nnesha):

then you have to look at rise over run you line is decreasing so slope must be negative

OpenStudy (anonymous):

yea because its a negative slope

Nnesha (nnesha):

and slope

OpenStudy (ffrocks3):

Do you have another question?

OpenStudy (anonymous):

yes

OpenStudy (anonymous):

OpenStudy (anonymous):

there it is

Nnesha (nnesha):

yes right

OpenStudy (ffrocks3):

You have it B

OpenStudy (anonymous):

ok next one

OpenStudy (ffrocks3):

ok

OpenStudy (anonymous):

OpenStudy (anonymous):

theres 5 quisions total 2 more

Nnesha (nnesha):

lines is down

OpenStudy (ffrocks3):

D because there is no slope so y = 3x

OpenStudy (ffrocks3):

-3X*

OpenStudy (ffrocks3):

sorry

Nnesha (nnesha):

where you draw lines where y values are negative so soppose to be negative

OpenStudy (anonymous):

o ok @Ffrocks3 give @Nnesha a medal plz

Nnesha (nnesha):

no its okay i wasn't helping for medals

OpenStudy (anonymous):

next one

OpenStudy (ffrocks3):

Hahaha nah you did the math i will ;) And you helped first

OpenStudy (anonymous):

OpenStudy (anonymous):

thanks guys

Nnesha (nnesha):

YOU HAVING THE ANSWER I WAS HERE TO EXPLAIN SO YOU CAN DO REST OF MM OWN

OpenStudy (ffrocks3):

Ok lets go over what he said: the y intercept is the point in which the line is crossed over the line that goes straight up ok?

OpenStudy (anonymous):

ok

OpenStudy (ffrocks3):

Slope(m) or x for you : is how much you go up and to the side. You go up 1 in this case and over 2

OpenStudy (ffrocks3):

So you take that 1 going up and place it in (1)/(?)

OpenStudy (ffrocks3):

then you do the side which is two and you plug it in 1/2

OpenStudy (anonymous):

so its 1,1

OpenStudy (ffrocks3):

you put that in front of the x always

OpenStudy (ffrocks3):

it is 1/2

OpenStudy (ffrocks3):

1 / 2 Rise ^ ^ Run

OpenStudy (anonymous):

so y=1/2x+

OpenStudy (ffrocks3):

Try to think of it like that

OpenStudy (ffrocks3):

and yes now the last part find y intercept

OpenStudy (ffrocks3):

where it crosses the line that goes up/down

OpenStudy (anonymous):

yea

OpenStudy (anonymous):

@Ffrocks3

OpenStudy (ffrocks3):

?

OpenStudy (ffrocks3):

You can do it ! ;)

OpenStudy (anonymous):

arent u gonna finish help ming me

OpenStudy (ffrocks3):

Yes, just find where it crosses the line

OpenStudy (anonymous):

-1 right

OpenStudy (ffrocks3):

Yes! so you plug that in after so y=1/2x -1

OpenStudy (ffrocks3):

Good job!

OpenStudy (anonymous):

sup dude sry idk this subject

OpenStudy (anonymous):

so its y=1/2x+-1

OpenStudy (ffrocks3):

well if it is negative ( - ) you don't need the + sign

OpenStudy (anonymous):

i got 1 more

OpenStudy (ffrocks3):

ok np

OpenStudy (anonymous):

OpenStudy (anonymous):

there it is

OpenStudy (ffrocks3):

This one you have to move the 8 to the other side because you want y alone

OpenStudy (anonymous):

yes but how

OpenStudy (ffrocks3):

Wait no its in point slope so you want \[y-y1 = m(x-x1)\]

OpenStudy (ffrocks3):

so you have some of those already plugin em' in y-8=-4/2(x-x1)

OpenStudy (ffrocks3):

\[y-8=-4/2(x-6)\]

OpenStudy (ffrocks3):

There ye go!

OpenStudy (anonymous):

back srry had to shut my garage

OpenStudy (ffrocks3):

np answer is there ^

OpenStudy (anonymous):

i can only have -4/ not -4/2

OpenStudy (ffrocks3):

really? weird.

OpenStudy (anonymous):

yea wat should i do

OpenStudy (ffrocks3):

can you do -2/1?

OpenStudy (ffrocks3):

which is simplified i should have mentioned

OpenStudy (anonymous):

nope should i leave out the negati ve or like wat

OpenStudy (ffrocks3):

no thats needed give me a sec

OpenStudy (ffrocks3):

ohhh duhh its -2 because you dont need the 1 under neath because it already stands for that

OpenStudy (ffrocks3):

so its \[y-8=-2(x-6)\]

OpenStudy (ffrocks3):

Good?

OpenStudy (anonymous):

ok let me try thaat

OpenStudy (anonymous):

great beat bro listen to it https://www.youtube.com/watch?v=lb7ZpMThGgk

OpenStudy (ffrocks3):

Yea it is! ;) Have a good one man if you need me ill be here just do @Ffrocks3 and fan if youd like
