OpenStudy (welshfella):

first find the slope m by difference of y values / difference of x va;lues = -6-(-7) ------- -8 - (-5)

OpenStudy (anonymous):

makes sence

OpenStudy (welshfella):

then plug this into y - y1 = m(x - x1) where (x1,y1) is a point on the line

OpenStudy (anonymous):

so is my answer b

OpenStudy (welshfella):

No take a closer look

OpenStudy (anonymous):

my bad its d

OpenStudy (welshfella):

look at the value of x1 and y1 in the equation and check them against the given points

OpenStudy (anonymous):

im so confused now

OpenStudy (welshfella):

the 5 and the 7 some be in same equation and so must the 6 and the 8

OpenStudy (welshfella):

* 7 must be

OpenStudy (anonymous):

so its a

OpenStudy (anonymous):

becuase its a negative

OpenStudy (welshfella):

if y1 = -7 y - y1 = y - (-7) = y + 7

OpenStudy (anonymous):

ok imma stop guessing and go with c lol

OpenStudy (welshfella):

lol c is the only one left

OpenStudy (welshfella):

y - y1 = m(x - x1) m = -1/3 , y1 = -7 amd x1 = -5 so equation is y + 7 = -1/3 ( x + 5)

OpenStudy (anonymous):

lol pfft i didnt say e lol im joking thnc for the help mate i got one more question after this

OpenStudy (welshfella):

and for the point (-6.-8) replace the 7 and 5 by 8 and 6

OpenStudy (welshfella):

well i gtg go its nearly 1 am in the UK

OpenStudy (welshfella):

i gotta get some rest..

OpenStudy (anonymous):
