y = mx + b
m=(y2-y1)/(x2-x1)

no..but i will..:)

can you set up the equation? then ill solve:P

(x1,y1) = (–1, –4)
(x2,y2) = (1, 4)

soo y=mx=b? isnt that for finding slope?

yes but you need to find m 1st
\[y=\frac{ y2-y1 }{ x2-x1 }\]

meant m =

ook ill try it..hold on..:)

m=-6

now what?

show me how?

m is wrong :D

really?

m= 1-4/-1--4.
m=-3/3
m=-6

(x1,y1) = (–1, –4)
(x2,y2) = (1, 4)
x1 = -1
y1 = -4
x2 = 1
y2 = 4

hi lolly :P

right..thats what i did..,.i think..?

hi..:)

(y-y1)/(y2-y1)=(x-x1)/(x2-x1)

(4- - 4)/(1- -1)= 8/2=4

so m is 4?

what you did (x2-y2)/(x1-y1)

well i thought it was -6..but its not..?

m = 4
now you choose wither point and solve for b
y = 4x + b

k hold on ill try again..:)

\[m=\frac{ y2-y1 }{ x2-x1 }=\frac{ 4- -4 }{ 1- -1 }=\frac{ 8 }{ 2 }=\]

for slope
slope=(y2-y1)/(x2-x1)
it can be directly solve see the formula that i have given already

(y-y1)/(y2-y1)=(x-x1)/(x2-x1)

oooh!!! i got the x1and 2s switched up..ok i see..:)

|dw:1351797990809:dw|

the one with less numbers right?

there is no zeros for x or y this time so pick one and solve, it doesnt matter which one

which one would be easier?

either, same thing

k ill do the one with less numbers..:P

so 4=4x1=b? 4=b..but we already knew that..

both of them has same amount of numbers :p
4=4x1=b? !
why is there an equal to b

oooh! whoop..my bad..:)

so 4=4+4...

4=8? that dosent make sense...

4=4x1+ b
what is x1 = ?

-1

y1 =?

-1

000h!!!

no it dosent..:)

-4

it should be one of the pairs either (1,4) or (-1,-4)
-4 = 4*(-1) + b

-4=4x-1=4?

4*-1=?

-4

-4 = -4 + b
how can you keep b on one side?

by adding 4 to b?

ok show me how?

-4=-4+b (then the 4 crosses out)
+4 +4

-4 +4 = -4 + 4 +b
0 = b
y = 4x + 0

where did the other set of -4=4 come from?

you have to add 4 to both sides

passes through points (–1, –4) and (1, 4)?

Anamaria what grade you in?

10.:)

you should know how to add :P

lol i do know how to add:)

-4=-4+b (then the 4 crosses out)
+4 +4
was this rong?

i went to pray
|dw:1351801108941:dw|

lol were u praying that id understand how to do this? lol jk ook umm anyway i thought b=4?

4 is not 8...? im so confused!!

do you want me to give you problem to do?

noo i dont want another problem im too stuck with this one..:)

tell what you dont understand
|dw:1351802673845:dw|

i dont really understand what you did..like at all... for the one on the right side...

ok so b = 4 and 0?

no only 0
how do you get the 4?

what we did earlier..

we never got b = 4
we got m is 4

oooh!!!

k thanks 4 ur help:)
