Answer:

\alpha_{2} = \frac{5}{4}\cdot \alpha_{1}, for all \alpha_{1} \in \mathbb{R}

Step-by-step explanation:

Vectors are parallel to each other if:

\vec u = \beta \cdot \vec v

(\alpha_{2}, 5) = (\beta\cdot \alpha_{1}, \beta \cdot 4)

The value of \beta is:

\beta = \frac{5}{4}

Then, the following relationship is found:

\alpha_{2} = \frac{5}{4}\cdot \alpha_{1}, for all \alpha_{1} \in \mathbb{R}
