Which equation is graphed here?

OpenStudy (anonymous):

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.

OpenStudy (anonymous):

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 ...

OpenStudy (anonymous):

oh my god..... im such an idiot I typed it wrong! your right im sooo sorry :(

OpenStudy (paxpolaris):

what did you type wrong?

OpenStudy (anonymous):

5/6

OpenStudy (anonymous):

OpenStudy (paxpolaris):

okay can you see that the slope is -3/2 ?

OpenStudy (anonymous):

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

OpenStudy (paxpolaris):

right it passes thru (negative2,4) ....

OpenStudy (paxpolaris):

so your answer is \[\large y-4=-\frac32\left( x+2 \right)\]
