Oh lol this is what they want ok
pooja195 (pooja195):
lets find our slope first
OpenStudy (anonymous):
that site didn't start with any of those. or I just don't know what I'm doing or how that site works.
pooja195 (pooja195):
\[\frac{ y2-y1 }{ x2-x1}\]

plug in the number values
OpenStudy (anonymous):
isn't the slope -6/6 ?
pooja195 (pooja195):
Yeah simplfy it
OpenStudy (anonymous):
this website is lagging for me so sorry if the replies are slow
pooja195 (pooja195):
its ok :)

simplified it's -1?
pooja195 (pooja195):
Major lag T_T yes thats right now the point slop equation is
\[y-y1=m(x-x1)\]
We know our slope is -1
what is y1?
what is x1?
OpenStudy (anonymous):
y1 is 3 and -8?
pooja195 (pooja195):
No there is only ONE value for each
\[(x1,y1) (x2,y2)\]
OpenStudy (anonymous):
no sorry I meant y1 is 3 and x1 is -8

Yep now plug them into the formula
\[y-y1=m(x-x1)\]
m=-1
y1=3
x1=-8
OpenStudy (anonymous):
y-3 = -1(x- (-8))
pooja195 (pooja195):
right and a negative next to a negative turns into a postive 8
pooja195 (pooja195):
once you have that you will know your answer :)
OpenStudy (anonymous):
yes forgot about the negative. (again sorry the lagging is really bad for me), but yeah I have my answer :). Thanks so much for your help
