Answer:
y = -x - 8
Step-by-step explanation:
First, calculate the slope:
m =
(x₁, y₁) will be (8, -16)
(x₂, y₂) will be (6, -14)
Plug in values:
m =
simplify:
m =
m = -1
plug values into y = mx + b:
-16 = (-1)(8) + b
solve for b:
b - 8 = -16
b = -8
rewrite the equation:
y = -1x - 8
y = -x - 8
Answer:
5.5, 7, 8.5
Step-by-step explanation:
Find the mean of 4 and 10, that is
=
= 7
Now repeat with 4 and 7 and 7 and 10
=
= 5.5
=
= 8.5
Hence
4, 5.5, 7, 8.5, 10 ← is an arithmetic sequence with d = 1.5
