iYuko (iyuko):

(x,y) you can take any two points and make your equation right?@Nnesha

iYuko (iyuko):

@Nnesha

Nnesha (nnesha):

yep! do you know the formula to find slope ? @jdbfhbhjdfvb

OpenStudy (anonymous):

no o;

iYuko (iyuko):

Its y=mx+b

iYuko (iyuko):

Pick any 2 points x,y ans sum them in ur equation and solve for b

iYuko (iyuko):

And sub*

iYuko (iyuko):

Right?

OpenStudy (anonymous):

soooo 15=3x+b ?

iYuko (iyuko):

No, for X AND Y Not m

Nnesha (nnesha):

y =mx+b is slope intercept form equation slope formula is \[\huge\rm m = \frac{ y_2 -y_1 }{ x_2 -x _1}\] first step )find slope

iYuko (iyuko):

Ahhhh. For get what I said @jdbfhbhjdfvb

Nnesha (nnesha):

like iyuko said pink any two points where \[\huge\rm (x_1 ,y_1 )(x_2 ,y_2)\]

i need to turn this in in 5 mins i need an answer ):

Nnesha (nnesha):

replace variables by their values = your answer

iYuko (iyuko):

^ Takes 2 mins
