Sure! Here’s a system of two linear inequalities:
1. \( 2x + 3y < 12 \)
2. \( x - y \geq 4 \)
These inequalities can be graphed on a coordinate plane to find the solution region, which will be the area where the shaded regions for both inequalities overlap.

To determine whether a given point is a solution to the system of linear inequalities from equation system 10:
1. **Identify the system**:
- \( 7x + y \geq 14 \) (Inequality 1)
- \( x - 3y < -5 \) (Inequality 2)
2. **Select a point**:
Let's say we want to test the point \( P(3, 5) \).
3. **Substitute the point into each inequality**:
- For Inequality 1: \( 7(3) + 5 \geq 14 \)
- Calculate: \( 21 + 5 \geq 14 \)
- This simplifies to \( 26 \geq 14 \), which is **true**.
- For Inequality 2: \( 3 - 3(5) < -5 \)
- Calculate: \( 3 - 15 < -5 \)
- This simplifies to \( -12 < -5 \), which is **false**.
4. **Conclusion**:
- Since the point \( P(3, 5) \) satisfies Inequality 1 but does not satisfy Inequality 2, it is **not a solution** to the system of inequalities.
### Example of a Point that is a Solution
Now let's check a different point, say \( P(5, 1) \).
1. **Substituting the point into each inequality**:
- For Inequality 1: \( 7(5) + 1 \geq 14 \)
- Calculate: \( 35 + 1 \geq 14 \)
- This simplifies to \( 36 \geq 14 \), which is **true**.
- For Inequality 2: \( 5 - 3(1) < -5 \)
- Calculate: \( 5 - 3 < -5 \)
- This simplifies to \( 2 < -5 \), which is **false**.
In this case, the point \( P(5, 1) \) similarly did not satisfy both inequalities, indicating it is **not a solution** to the system either.
### Finding a Valid Solution
Let's try \( P(4, 6) \):
1. **Substituting the point into each inequality**:
- For Inequality 1: \( 7(4) + 6 \geq 14 \)
- Calculate: \( 28 + 6 \geq 14 \)
- This simplifies to \( 34 \geq 14 \), which is **true**.
- For Inequality 2: \( 4 - 3(6) < -5 \)
- Calculate: \( 4 - 18 < -5 \)
- This simplifies to \( -14 < -5 \), which is **true**.
Since point \( P(4, 6) \) satisfies both inequalities, it **is a solution** to the system of linear inequalities.
### Summary
To determine if a point is a solution to a system of linear inequalities, substitute the coordinates of the point into each inequality. If the point satisfies all inequalities in the system, it is considered a solution. If it fails to satisfy even one inequality, it is not a solution.

I cannot create visual graphs directly, but I can guide you through the steps to graph the system of linear inequalities and identify the solution set on graph paper. Here’s how to do it for the system of inequalities from equation system 10:
### Step 1: Write down the inequalities
1. \( 7x + y \geq 14 \) (Inequality 1)
2. \( x - 3y < -5 \) (Inequality 2)
### Step 2: Convert inequalities to equations
First, rewrite the inequalities as equations to find the boundary lines.
- For \( 7x + y = 14 \):
- When \( x = 0 \): \( y = 14 \) (point \( (0, 14) \))
- When \( y = 0 \): \( 7x = 14 \) → \( x = 2 \) (point \( (2, 0) \))
- For \( x - 3y = -5 \):
- When \( x = 0 \): \( -3y = -5 \) → \( y = \frac{5}{3} \) (point \( (0, \frac{5}{3}) \))
- When \( y = 0 \): \( x = -5 \) (point \( (-5, 0) \))
### Step 3: Plot the lines
1. Plot the points of the first equation \( 7x + y = 14 \) (i.e., \( (0, 14) \) and \( (2, 0) \)) and draw the boundary line. Since the inequality is \(\geq\), use a solid line.
2. Plot the points of the second equation \( x - 3y = -5 \) (i.e., \( (0, \frac{5}{3}) \) and \( (-5, 0) \)) and draw the boundary line. Since the inequality is \(<\), use a dashed line.
### Step 4: Shade the solution regions
- For the first inequality \( 7x + y \geq 14 \): Shade **above** the solid line (including the line itself).
- For the second inequality \( x - 3y < -5 \): Shade **below** the dashed line (excluding the line itself).
### Step 5: Identify the solution region
The solution set to the system of inequalities will be the area where the two shading regions overlap. This overlapping region is the set of points that satisfy both inequalities at the same time.
### Conclusion
Once you have shaded the regions on your graph paper based on these steps, you should clearly mark the overlapping area. You can indicate it as the "solution set" or "feasible region."
If you wish to test points within that solution set, you can select any point from the shaded area and substitute it back into both inequalities to confirm it satisfies them. This will help reinforce your understanding of the solution set!
### Step 1: Write down the inequalities
1. \( 7x + y \geq 14 \) (Inequality 1)
2. \( x - 3y < -5 \) (Inequality 2)

Yes, the graph of a system of two linear inequalities will contain two lines, each representing one of the inequalities in the system. Here's a clearer breakdown of how the lines function in the graph:
1. **Two Boundary Lines**:
- Each inequality corresponds to a specific line on the graph.
- The first line comes from the equation \( 7x + y = 14 \), which you can plot with a solid line because the inequality is \(\geq\) (indicating that points on the line are included in the solution).
- The second line comes from the equation \( x - 3y = -5 \), which you plot with a dashed line because the inequality is \(<\) (indicating that points on that line are not included in the solution).
2. **Shading**:
- After drawing the lines, you would shade the appropriate regions:
- For the line \( 7x + y = 14 \), you would shade **above** the solid line to represent all the points where \( 7x + y \geq 14 \).
- For the line \( x - 3y = -5 \), you would shade **below** the dashed line to represent all the points where \( x - 3y < -5 \).
3. **Intersection of Shaded Regions**:
- The solution set will be the area where the shadings from both inequalities overlap. This overlapping region is where all points satisfy both inequalities simultaneously.
### Conclusion
To summarize:
- Yes, the graph should contain two lines (one solid and one dashed).
- The solution set is found in the overlapping shaded region created by these two inequalities.
If you were to graph it on paper, you would indeed represent both boundary lines to visually display the inequalities and their corresponding solution regions.

I apologize for any confusion. Let's clarify the orientation of the two lines derived from the given inequalities:
### Given Inequalities
1. **Inequality 1**: \(7x + y \geq 14\)
2. **Inequality 2**: \(x - 3y < -5\)
### Graphing the Lines
1. **For \(7x + y = 14\)**:
- Rearrange to slope-intercept form: \(y = -7x + 14\)
- This line has a **negative slope** (specifically, -7), which means it will slant **downward** from left to right.
- **Characteristics**: It is a relatively steep line, crossing the y-axis at \(y = 14\) and the x-axis at \(x = 2\).
2. **For \(x - 3y = -5\)**:
- Rearrange to slope-intercept form: \(3y = x + 5\) or \(y = \frac{1}{3}x + \frac{5}{3}\)
- This line has a **positive slope** (specifically, \(\frac{1}{3}\)), which means it will slant **upward** from left to right.
- **Characteristics**: It is a gentler slope than the first line, crossing the y-axis at \(y = \frac{5}{3}\) (approximately \(1.67\)) and the x-axis at \(x = -5\).
### Summary of Slants
- The first line (from \(7x + y = 14\)) is **downward slanting** (negative slope).
- The second line (from \(x - 3y = -5\)) is **upward slanting** (positive slope).
### Conclusion
In the context of their orientations:
- **One line will be slanted downward** (the solid line for the first inequality).
- **The other line will be slanted upward** (the dashed line for the second inequality).
Both lines will cross each other somewhere in the coordinate plane, forming a specific region where the solution to the system of inequalities exists. This region will be the overlap of the shaded areas for both inequalities, clearly indicating the valid solutions for the system.
### Given Inequalities
1. **Inequality 1**: \(7x + y \geq 14\)
2. **Inequality 2**: \(x - 3y < -5\)
### Graphing the Lines
1. **For \(7x + y = 14\)**:
- Rearrange to slope-intercept form: \(y = -7x + 14\)
- This line has a **negative slope** (specifically, -7), which means it will slant **downward** from left to right.

- **Characteristics**: It is a gentler slope than the first line, crossing the y-axis at \(y = \frac{5}{3}\) (approximately \(1.67\)) and the x-axis at \(x = -5\).
### Summary of Slants
- The first line (from \(7x + y = 14\)) is **downward slanting** (negative slope).
- The second line (from \(x - 3y = -5\)) is **upward slanting** (positive slope).
### Conclusion
In the context of their orientations:
- **One line will be slanted downward** (the solid line for the first inequality).
- **The other line will be slanted upward** (the dashed line for the second inequality).
Both lines will cross each other somewhere in the coordinate plane, forming a specific region where the solution to the system of inequalities exists. This region will be the overlap of the shaded areas for both inequalities, clearly indicating the valid solutions for the system.
