Math Problem Statement
Solution
The inequality given in the image is .
Steps to graph the inequality:
-
Plot the boundary line: The equation of the boundary line is . Since the inequality is , the boundary line will be solid, meaning that points on the line are included in the solution.
- The slope is , so for every 4 units you move to the right, you go down by 3 units.
- The y-intercept is 5, so the line crosses the y-axis at .
-
Shade the region: Since the inequality is , you will shade the area below the line, where the y-values are less than or equal to the line.
Key Points:
- Start at on the y-axis.
- Move according to the slope: down 3 and right 4 to plot additional points like or .
- Draw the solid line through these points.
- Shade below the line.
Do you need further details on any part of this? Let me know! Here are some follow-up questions:
- Why is the line solid instead of dashed?
- How do you determine which side of the line to shade?
- What does the slope represent in the context of this inequality?
- How would the graph change if the inequality were ?
- Can you find the x-intercept of the boundary line?
Tip: Always remember that if the inequality sign is or , the boundary line should be solid, while for or , the line should be dashed.
