Any line that travels through the points (-6,2) and (-1,-4).
OpenStudy (anonymous):
What are the equations?
OpenStudy (anonymous):
a-y-2=-5/6(x+6) b-y+4=-5/6(x+1) c-y-6=-6/5(x+2) d-y-4=-5/6(x-1) e-y-2=-6/5(x+6) f-y+4=-6/5(x+1)
OpenStudy (anonymous):
there they are
OpenStudy (anonymous):
type them in separate lines so I can make them out from one another.

A .y-2=-5/6(x+6)
B .y+4=-5/6(x+1)
C .y-6=-6/5(x+2)
D .y-4=-5/6(x-1)
E .y-2=-6/5(x+6)
F .y+4=-6/5(x+1)

\[y - 2 = -\frac{ 5 }{ 6 }(x + 6)\]
That's the format for the equations?
OpenStudy (anonymous):
yea
OpenStudy (anonymous):
im from britain and im new to this type of math
OpenStudy (anonymous):
Isolate y by adding 2 to both sides.
y = -5/6(x + 6) + 2
Now you have it in slope intercept form.

is that the only answer because it said check all that apply
OpenStudy (anonymous):
No, you still have to plug it all in.
OpenStudy (anonymous):
Okay, let me show you how.
OpenStudy (anonymous):
k
OpenStudy (anonymous):
(-6, 2)
A) y-2=-5/6(x+6)
y = -5/6(x + 6) + 2
f(-6) = -5/6(-6 + 6) + 2
f(-6) = -5/6 + 2
f(-6) = 7/6
When x = -6 y = 7/6.
(-6, 7/6) = (-6,2)
False

kk
OpenStudy (anonymous):
So, next one.
y+4=-5/6(x+1)
y = -5/6(x + 1) - 4
x = -6
y = -5/6(-6 + 1) - 4
y = -5/6 * -5 - 4
y = -5/6 * -9
y = 15/2
(-6,2) = (-6,15/2)
False

Do you see how to do it now?
OpenStudy (anonymous):
not really
