System Inequalities Bccd0B
1. **Stating the problem:**
We need to find the system of inequalities that describes the shaded region in the given graph.
2. **Analyzing the graph:**
- The shaded region is bounded by a line passing through points $(0,6)$ and $(6,0)$.
- The region is above the line $y=4$.
- The region is also in the first quadrant, so $x \geq 0$ and $y \geq 0$.
3. **Finding the equation of the line through $(0,6)$ and $(6,0)$:**
The slope $m$ is given by
$$m = \frac{0-6}{6-0} = \frac{-6}{6} = -1$$
Using point-slope form with point $(0,6)$:
$$y - 6 = -1(x - 0) \implies y = -x + 6$$
4. **Determining the inequality for the line:**
Since the shaded region is above this line, the inequality is
$$y \geq -x + 6$$
5. **Inequality for the horizontal boundary:**
The region is above the line $y=4$, so
$$y \geq 4$$
6. **Inequalities for the axes:**
Since the region is in the first quadrant,
$$x \geq 0, \quad y \geq 0$$
7. **Final system of inequalities:**
$$\begin{cases}
y \geq -x + 6 \\
y \geq 4 \\
x \geq 0 \\
y \geq 0
\end{cases}$$
This system describes the shaded region in the graph.
