A. y + 4 = -5/6(x + 8)
b. y - 4 =-5/6(x + 6)
c. y + 4 = -5/6(x - 8)
d. y - 4 = 5/6(x - 8)

OpenStudy (paxpolaris):
is the slope positive or negative?
OpenStudy (anonymous):
negative
OpenStudy (paxpolaris):
so we can rule out d.

please help me :(
OpenStudy (paxpolaris):
I don't think the graph matches the question: the slope in the graph is -3/2..... (it really doesn't look like -5/6)
OpenStudy (anonymous):
me neither :/
OpenStudy (anonymous):
its on my test and I don't know how to answer it :(
OpenStudy (paxpolaris):
the graph is wrong ...

yes
OpenStudy (anonymous):
can you give me the full answer
OpenStudy (paxpolaris):
so we are left with two choices:\[\large y-1=-\frac32\left( x+3 \right)\]
and: \[\large y-4=-\frac32\left( x+2 \right)\]
OpenStudy (paxpolaris):
which point does the line pass through: \((-3,1)\) or \((-2,4)\)
OpenStudy (anonymous):
I don't no em 2 and 4

right it passes thru (negative2,4) ....
OpenStudy (paxpolaris):
so your answer is \[\large y-4=-\frac32\left( x+2 \right)\]
