To solve the inequalities provided and to represent their solutions graphically, let's start by identifying and solving each inequality. Then, we'll describe how to graph the solutions and shade the appropriate regions.

1. \( 4x \leq 4 \)
2. \( 2y + 3 \leq x + 2 \)
3. \( 3 \leq x - y - 5 \)
4. \( 2x - 7y \geq 3 \)
5. \( 3x + y \geq 5 \)
6. \( 6 \leq 7x + 2y \)
7. \( y \geq x - 5 \)

Let's solve each inequality step-by-step:

### 1. \( 4x \leq 4 \)
Divide both sides by 4:
\[ x \leq 1 \]

### 2. \( 2y + 3 \leq x + 2 \)
Subtract 2 from both sides:
\[ 2y + 1 \leq x \]
Rearrange to isolate \( y \):
\[ y \leq \frac{x - 1}{2} \]

### 3. \( 3 \leq x - y - 5 \)
Add 5 to both sides:
\[ 8 \leq x - y \]
Rearrange to isolate \( y \):
\[ y \leq x - 8 \]

### 4. \( 2x - 7y \geq 3 \)
Rearrange to isolate \( y \):
\[ -7y \geq 3 - 2x \]
Divide by -7 (reversing the inequality sign):
\[ y \leq \frac{2x - 3}{7} \]

### 5. \( 3x + y \geq 5 \)
Rearrange to isolate \( y \):
\[ y \geq 5 - 3x \]

### 6. \( 6 \leq 7x + 2y \)
Rearrange to isolate \( y \):
\[ 2y \geq 6 - 7x \]
Divide by 2:
\[ y \geq 3.5 - \frac{7x}{2} \]

### 7. \( y \geq x - 5 \)
This inequality is already solved for \( y \).

### Graphical Representation
To graph these inequalities, follow these steps for each inequality:

1. **Graph the boundary line** (treat the inequality as an equality).
2. **Determine the shading**:
   - For \( y \leq \) inequalities, shade below the line.
   - For \( y \geq \) inequalities, shade above the line.
   - For \( x \leq \) or \( x \geq \) inequalities, shade to the left or right of the line respectively.

Let's describe the graphing for each:

1. \( x \leq 1 \): A vertical line at \( x = 1 \). Shade to the left.
2. \( y \leq \frac{x - 1}{2} \): A line with a slope of 1/2 and y-intercept of -1/2. Shade below.
3. \( y \leq x - 8 \): A line with a slope of 1 and y-intercept of -8. Shade below.
4. \( y \leq \frac{2x - 3}{7} \): A line with a slope of 2/7 and y-intercept of -3/7. Shade below.
5. \( y \geq 5 - 3x \): A line with a slope of -3 and y-intercept of 5. Shade above.
6. \( y \geq 3.5 - \frac{7x}{2} \): A line with a slope of -7/2 and y-intercept of 3.5. Shade above.
7. \( y \geq x - 5 \): A line with a slope of 1 and y-intercept of -5. Shade above.

By plotting these lines and shading the corresponding regions, you can identify the solution set for each inequality. If you have graphing paper or a graphing tool, you can plot these lines and shade the regions accordingly.
