Ok, so here, we need to use the slope formula which is:

(y2 - y1)/(x2-x1)

y2 = 9
y1 = 5

x2 = x
x1 = 10

So:

(9-5)/(x-10) = -2

Now, we just solve for x,

9-5  =  -2(x-10)

4  =  -2x+20

2x  =  16

x  =  8

Number of years (n) 5 years

Interest rate (i)= 8.5% compounded annually

<u>To calculate the initial investment (PV), we need to use the following formula:</u>
