1. **State the problem:**
We are given inequalities involving $x$ and $y$:
$$25x + 12.50y \geq 1000$$
$$x + y \leq 15000$$
We want to express these inequalities in slope-intercept form ($y = mx + b$) and understand the feasible region.
2. **Rewrite the first inequality:**
Start with:
$$25x + 12.50y \geq 1000$$
Subtract $25x$ from both sides:
$$12.50y \geq 1000 - 25x$$
Divide both sides by $12.50$:
$$y \geq \frac{1000 - 25x}{12.50}$$
Show cancellation:
$$y \geq \frac{\cancel{1000} - \cancel{25}x}{\cancel{12.50}}$$
Simplify:
$$y \geq 80 - 2x$$
3. **Rewrite the second inequality:**
Start with:
$$x + y \leq 15000$$
Subtract $x$ from both sides:
$$y \leq 15000 - x$$
4. **Summary:**
The inequalities in slope-intercept form are:
$$y \geq -2x + 80$$
$$y \leq -x + 15000$$
5. **Interpretation:**
- The first inequality represents the region above or on the line $y = -2x + 80$.
- The second inequality represents the region below or on the line $y = -x + 15000$.
6. **Final answer:**
The system of inequalities is:
$$\boxed{y \geq -2x + 80 \quad \text{and} \quad y \leq -x + 15000}$$
This describes the feasible region bounded by these two lines.
