1. **State the problem:** Solve the inequality $-4 + 2x \geq 1$.
2. **Add 4 to both sides:**
$$-4 + 2x + 4 \geq 1 + 4$$
$$\cancel{-4} + 2x + \cancel{4} \geq 5$$
$$2x \geq 5$$
3. **Divide both sides by 2:**
$$\frac{2x}{2} \geq \frac{5}{2}$$
$$\cancel{2}x \geq \frac{5}{2}$$
$$x \geq \frac{5}{2}$$
4. **Interpret the solution:**
The solution to the inequality is all $x$ values greater than or equal to $\frac{5}{2}$ (which is 2.5).
5. **Check the options:**
- I. $-4$ is less than $2.5$, so it does not satisfy the inequality.
- II. $-6$ is less than $2.5$, so it does not satisfy the inequality.
- III. $3$ is greater than $2.5$, so it satisfies the inequality.
**Final answer:** $x \geq \frac{5}{2}$ or $x \geq 2.5$.
Only option III satisfies the inequality.
