1. **State the problem:** We are given a system of inequalities:
$$5x + y \leq 10$$
$$x + y \leq 6$$
$$x \geq 0$$
$$y \geq 0$$
We want to understand the feasible region defined by these inequalities.
2. **Explain the inequalities:**
- The first inequality $5x + y \leq 10$ represents all points on or below the line $y = 10 - 5x$.
- The second inequality $x + y \leq 6$ represents all points on or below the line $y = 6 - x$.
- The third and fourth inequalities $x \geq 0$ and $y \geq 0$ restrict the region to the first quadrant.
3. **Find intercepts for each line:**
- For $5x + y = 10$:
- When $x=0$, $y=10$.
- When $y=0$, $5x=10 \Rightarrow x=2$.
- For $x + y = 6$:
- When $x=0$, $y=6$.
- When $y=0$, $x=6$.
4. **Find intersection of the two lines:**
Solve the system:
$$\begin{cases} 5x + y = 10 \\ x + y = 6 \end{cases}$$
Subtract second from first:
$$5x + y - (x + y) = 10 - 6$$
$$5x + y - x - y = 4$$
$$4x = 4$$
$$x = 1$$
Substitute $x=1$ into $x + y = 6$:
$$1 + y = 6 \Rightarrow y = 5$$
5. **Summary of key points:**
- Intercepts of $5x + y = 10$: $(0,10)$ and $(2,0)$
- Intercepts of $x + y = 6$: $(0,6)$ and $(6,0)$
- Intersection point: $(1,5)$
6. **Feasible region:**
The feasible region is bounded by the lines $5x + y \leq 10$, $x + y \leq 6$, and the axes $x \geq 0$, $y \geq 0$. It is a polygon with vertices at $(0,0)$, $(0,6)$, $(1,5)$, and $(2,0)$.
This region can be graphed on the coordinate plane with the given axis ranges and labels.
