2/3 - 1/6
2/3 + -1/6
4/6 + -1/6
3/6
= 1/2 or 0.5
See attached picture for the solution
One solution because the lines only cross once, at (0,3)
By observing the graph we can note down the following things about the boundary line:
- It has a positive slope.
- It cuts the X-axis at

- It cuts the Y-axis at $(0,-x)$, where $|x|$ is some value less than 2 but greater than 1.
Let's look at the shaded region. The origin lies inside it.
Thus, the point $(0,0)$ satisfies the equation of the region.
Upon putting it in the options, we find that only two options: 2 and 4 satisfy the inequality $0<5$
Now find the Y-intercept of the boundary line:
Option 4) $0-2y=5$
$y=\frac{-5}{2}<-2$
Since it is smaller than -2, it is the wrong option.
Hence, correct option is $\boxed{x-3y<5}$
V = 14 × 12.5 × 1 => V = 175
