First, recall that the equation of a line is
y = mx+b
where
m = slope
b = y-int
The key to this question is the details :
Horizontal line ---> This tells you that your slope is 0
y-int = 3.5 -----> In the equation above, b=3.5
Therefore,
y = 0x + 3.5
y = 0 + 3.5
y = 3.5
Using an exponential function, it is found that you would have $10,240 after 18 years.
<h3>What is an exponential function?</h3>
An increasing exponential function is modeled by:
![A(t) = A(0)(1 + r)^t](https://tex.z-dn.net/?f=A%28t%29%20%3D%20A%280%29%281%20%2B%20r%29%5Et)
In which:
- A(0) is the initial value.
- r is the growth rate, as a decimal.
Considering the initial value of $2,500, and the growth rate of 60% every 6 years, the equation is given by:
![A(t) = 2500(1.6)^\frac{t}{6}](https://tex.z-dn.net/?f=A%28t%29%20%3D%202500%281.6%29%5E%5Cfrac%7Bt%7D%7B6%7D)
Hence, after 18 years, the amount is given by:
![A(18) = 2500(1.6)^\frac{18}{6} = 10240](https://tex.z-dn.net/?f=A%2818%29%20%3D%202500%281.6%29%5E%5Cfrac%7B18%7D%7B6%7D%20%3D%2010240)
