Answer:
The equation is y=-1/2x-4
Step-by-step explanation:
(-4,-2) m=-1/2
y=mx+b
y=-1/2x+b
-2=-1/2(-4/1)+b
-2=2+b
-2 -2
-4=b
ANSWER
My answer is in the photo above
Working shown, hopefully it helps
Answer:
C
Step-by-step explanation:
This is a geometric sequence with n th term
= a 
Where a is the first term and r is the common ratio
r =
=
=
=
, hence
f(n) = 16
→ C
C should be -10
Hope this helps
