Answer:
 or -0.625
 or -0.625
Step-by-step explanation:
The slope formula is as shown:

We can have A = ( ,
, ) and B = (
) and B = ( ,
, ).
).
We can hence plug in the values into the formula to get  .
.
As we simplify, the negatives on the top row cancel out to give us an addition sign instead and we add them.

compound interest equation for annually compounded

A=final amount
P=principal
r=rate in decimal
t=time in years
given that 
A=1550
P=1000
r=5.5%=0.055
find t

divide both sides by 1000

take ln of both sides

use ln rule 

divide both sides by ln(1.055)

using a calculator, we get that t=8.18544 yrs
so about 8.2yrs
