1. **State the problem:** We need to graph the system of linear inequalities:
$$y > -2x - 1$$
$$-4x + y \geq 1$$
2. **Rewrite inequalities for clarity:**
The first inequality is already solved for $y$:
$$y > -2x - 1$$
Rewrite the second inequality:
$$-4x + y \geq 1 \implies y \geq 4x + 1$$
3. **Analyze the inequalities:**
- The first inequality $y > -2x - 1$ means the region above the line $y = -2x - 1$ (not including the line).
- The second inequality $y \geq 4x + 1$ means the region above or on the line $y = 4x + 1$.
4. **Find the intersection point of the boundary lines:**
Set the lines equal:
$$-2x - 1 = 4x + 1$$
Solve for $x$:
$$-2x - 1 = 4x + 1$$
$$-2x - 4x = 1 + 1$$
$$-6x = 2$$
$$x = -\frac{1}{3}$$
Find $y$:
$$y = 4\left(-\frac{1}{3}\right) + 1 = -\frac{4}{3} + 1 = -\frac{1}{3}$$
So the lines intersect at $\left(-\frac{1}{3}, -\frac{1}{3}\right)$.
5. **Determine the correct shaded region:**
- For $y > -2x - 1$, the region is above the line $y = -2x - 1$.
- For $y \geq 4x + 1$, the region is above or on the line $y = 4x + 1$.
The solution to the system is the intersection of these two regions.
6. **Choose the correct graph option:**
- The first graph shows shading above $y = -2x - 1$ and above $y = 4x + 1$ with lines intersecting near $(0, -1)$.
- The intersection point we found is near $\left(-\frac{1}{3}, -\frac{1}{3}\right)$, close to $(0, -1)$.
- The shading in the first graph matches the solution region (above both lines).
**Final answer:** The correct graph is the **first graph (top-left)**.
