In this example, we have the two equations, $y \geq 2x - 1$ and $y \leq -3x + 1$.
For the first equation, $y \geq 2x - 1$, the symbol $\geq$ (greater than or equal) means that the area above the line will be shaded. As for the second equation, $y \leq -3x + 1$, the symbol $\leq$ (less than or equal) means that the area below the line will be shaded.
