Answer:
y=1/2x+6
Step-by-step explanation:
Change to slope intercept form: y=1/2x-2
Take out the b term
Plug in point (-8, 2)
Get b as 6
Plug in b
Get y=1/2x+6
The answer to the first question is b
I don’t know the answer to the second one sorry
<span>average rate of change = (f(7) - f(5)) / (x7 - x5)
</span>f(7) = <span>12 (7^3) + 12 = 4128
f(5) = </span>12 (5^3) + 12 = 1512
so
average rate of change = (4128 - 1512)/(7-5)
average rate of change = 2616 / 2
average rate of change = 1308
hope it helps
I would say it could be 35
