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
Join the QuestionCove community and study together with friends!
Sign Up
OpenStudy (anonymous):
yea because its a negative slope
Nnesha (nnesha):
and slope
OpenStudy (ffrocks3):
Do you have another question?
OpenStudy (anonymous):
yes

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

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
Join the QuestionCove community and study together with friends!

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

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