for this problem yo would have to find the slope of this line. Do you know how to do that?
OpenStudy (anonymous):
yes
the slope is -4/3
OpenStudy (anonymous):
Nah, it's -4/6
OpenStudy (anonymous):
im sorry -2/3
i dont know what i was thinking
OpenStudy (anonymous):
it happens :)

i simplified
OpenStudy (anonymous):
now what
OpenStudy (anonymous):
now can you, using the slope you have, write in point slope form?
OpenStudy (anonymous):
no
OpenStudy (anonymous):
y=mx+b
y=-2/3 x+b

do you know y-y1=m(x-x1)
OpenStudy (anonymous):
choose one of the points, plug in y and x accordingly, and solve for b
OpenStudy (anonymous):
ah then i put the (3,1) or (-3,5) in for x and y then i have my y intercept then im dont. ok thankyou i get it now
OpenStudy (anonymous):
ur welcome! good job!
OpenStudy (anonymous):
no you are not done, you wanted standard form not point slope form

do you know how to change from point slope form to standard form
OpenStudy (anonymous):
I thought y=mx+b was standard form ;(
OpenStudy (anonymous):
thats what im thinking
OpenStudy (anonymous):
no, standard form is AX+BY=C
OpenStudy (anonymous):
wo

Yeah, not everything in math is cut and dry
OpenStudy (anonymous):
are you sure
OpenStudy (anonymous):
what are the a,b,and c?
OpenStudy (anonymous):
yea i am sure, you said you wanted standard form right?
OpenStudy (anonymous):
yes
i know how to swich them i just thought they were each other
