Answer:
D) $2693.12
Step-by-step explanation:
The account balance is multiplied by 1.09 each year, so at the end of 5 years, it has been multiplied by 1.53862395....
After subtracting the initial deposit amount, the remainder is the interest earned:
... $5000×(1.53862395 -1) = $5000×0.53862395 ≈ $2693.12
Here is a simple equation for this problem

so this would be the equation

4--8 would change to 4+8 because of the double negative
12/8 is the slope for your line
Hope this helps!
