Two straight lines pass through the origin $(x_{0}, y_{0}) = (0, 0)$. One of them passes through the point $(x_{1}, y_{1}) = (1, 3)$ and the other passes through the point $(x_{2}, y_{2}) = (1, 2)$.
What is the area enclosed between the straight lines in the interval $[0, 1]$ on the $x$-axis?
- $0.5$
- $1.0$
- $1.5$
- $2.0$
