Math Problem Statement
Solve the system of two linear inequalities graphically: x > 2 or y ≥ 7.
Solution
The problem in the image involves solving a system of two linear inequalities graphically. The first step asks to graph the solution set of the first inequality, which is given as:
Here’s how to approach it:
Step-by-Step Explanation:
1. Graphing the Inequality :
- The line is a vertical line, and since the inequality is , the region to the right of this line needs to be shaded.
- For the boundary:
- The line is dashed because the inequality is strict (i.e., it does not include ).
- Enter two points on this vertical line, such as:
- Point 1:
- Point 2:
- Select the region to the right of this line for shading (this will be the shaded region for ).
2. Graphing the Inequality :
- The line is a horizontal line.
- The inequality includes the line, so the line should be solid.
- The region above the line needs to be shaded.
- Enter two points on this horizontal line, such as:
- Point 1:
- Point 2:
Shading the Region:
- The solution to the system of inequalities involves the union of the regions for and .
- For , shade to the right of the dashed vertical line.
- For , shade above the solid horizontal line.

- What happens if the inequalities involve or for both and ?
Tip: Always remember to label your boundary lines clearly and distinguish between dashed and solid lines for strict vs. inclusive inequalities.
