### All-Integer Linear Program

Consider the following all-integer linear program:

**Objective:**
\[ \text{Maximize } 1x_1 + 1x_2 \]

**Subject to:**
1. \( 5x_1 + 6x_2 \leq 41 \)
2. \( 1x_1 + 7x_2 \leq 21 \)
3. \( 2x_1 + 1x_2 \leq 15 \)

**Constraints:**
\[ x_1, x_2 \geq 0 \text{ and integers} \]

---

### Task

#### (a) Graph the constraints for this problem. 
Use dots to indicate all feasible integer solutions.

**Graphical Analysis:**
The problem involves three graphs, each showing the feasible region (in blue) for combinations of \( x_1 \) and \( x_2 \). Dots within the blue area represent feasible integer solutions that satisfy all constraints.

1. **First Graph:**
   - **Axes:** \( x_1 \) (horizontal), \( x_2 \) (vertical)
   - **Feasible Region:** The bounded polygon indicates possible values for \( x_1 \) and \( x_2 \) satisfying the constraints.
   
2. **Second Graph:**
   - Same axes setup as the first graph, depicting the same feasible region.

3. **Third Graph:**
   - Same axes setup and depiction, reiterating the feasible region with integer solutions marked by dots.

#### (b) Solve the LP Relaxation of this problem.

\[ \text{Optimal Solution at } (x_1, x_2) = \left( \boxed{\phantom{00}} \right) \]

#### (c) Find the optimal integer solution.

\[ \text{Optimal Integer Solution at } (x_1, x_2) = \left( \boxed{\phantom{00}} \right) \]

Each graph and solution box aids in determining the optimal solutions based on the constraints and objectives provided. To solve the relaxation or the integer problem, one would typically use methods such as the Simplex algorithm or integer programming techniques.
