Are you aware of the formula ?
OpenStudy (anonymous):
Well i found the slope, -3/15
OpenStudy (anonymous):
its it y-3=-3/15(x-5)
OpenStudy (rabya!):
yes now simplify it.
OpenStudy (anonymous):
my answer isnt listed in the choices

what are the choices ?
OpenStudy (anonymous):
OpenStudy (rabya!):
did you copy the question right ?
OpenStudy (anonymous):
yes
OpenStudy (rabya!):
how did you find out slope ?

y2-y1/x2-x1
OpenStudy (rabya!):
m= y2-y1 / x2-x1
OpenStudy (anonymous):
i did that
OpenStudy (rabya!):
how ?
OpenStudy (anonymous):
3-6/5--10

its -10, not 10 sorry
OpenStudy (anonymous):
slope= -3/15
OpenStudy (rabya!):
m = 3-6/ 5-10
m= -3/-5
m=3/5
this should be the slope.
OpenStudy (anonymous):
Its -10
OpenStudy (anonymous):
not 10, i copied the 10 wrong

the only option for 3/5 is negative so that isnt right
OpenStudy (rabya!):
ok..
so y-y1 = -3/15 (x-x1)
Is that right ?
OpenStudy (anonymous):
yes
OpenStudy (rabya!):
so it should be
y-6 = -3/15 (x+10)
OpenStudy (anonymous):
yes

OpenStudy (rabya!):
or
y-6 = -1/5 ( x+10)
OpenStudy (rabya!):
right ?
OpenStudy (anonymous):
how did you get 1/5
OpenStudy (rabya!):
divide
3x1 =3
and 3x5 = 15
so simplify it
3/15 = 1/5
OpenStudy (anonymous):
Oh.. haha ok thanks
