No, if two lines are parallel then they will have NO solutions, because they DO NOT intersect. Parallel lines have the same slope and different y-intercepts, therefore making them not intersect.

Mathematics

The arithmetic average return would be 3.96%

Step-by-step explanation:

Given,

The returns in 5 years are,

-9.7%, -8.1%, 15%, 7.2%, and 15.4%

We know that,

$\text{Arithmetic average}=\frac{\text{Sum of all observations}}{\text{Number of observations}}$

Hence,

The arithmetic average return of the investment = $\frac{-9.7-8.1+15+7.2+15.4}{5}$

$=\frac{19.8}{5}$

= 3.96%
