Answer:
65.54% (nearest hundredth)
Step-by-step explanation:
Given:

P(X > 8600) = 1 - P(X ≤ 8600)
= 1 - 0.3445782584
= 0.6554217416
= 65.54%
Slope of line passing through two points (x1,y1 ) and (x2 ,y2 ) is given by
m= y2-y1/x2 −x1
Since the line passes through (−2,5) and (6,4)
We have
Slope(m)= 4-5/6−(−2) =− 1/8
I believe your answer is required in Rise/Run form.
Rise is -1 and Run is +2
so
-1/2
