Math Problem Statement
Solution
The system of two linear inequalities shown in the image is:
Let's break this down into the steps as suggested in the question:
Step 1: Graph the first inequality .
-
Find the boundary line for . This line is straight, and its slope is 7 with a y-intercept of 7. To graph the line:
- Start by plotting the point (0, 7) since the y-intercept is 7.
- Use the slope to find another point. The slope means rise over run (rise = 7, run = 1), so from (0, 7), move 1 unit to the right and 7 units up to get the point (1, 14).
-
Determine the boundary type:
- Since the inequality is (less than or equal), the boundary line should be solid because it includes the points on the line.
-
Shade the region:
- You will shade the region below the line because the inequality is (less than or equal means below the line).
Now, you can enter two points on the graph corresponding to the line (e.g., (0, 7) and (1, 14)) and choose a solid line. Finally, shade the appropriate region (below the line).
Once you finish this step, you'll proceed to graph the second inequality in a similar way.
Would you like further details on the second inequality and overall solution? Let me know if you have any questions.
Here are some follow-up questions to help deepen your understanding:
- What happens if the inequality symbol is switched to or ?
- How do you graph inequalities with negative slopes?
- What if the system involves -related inequalities like ?
- Can two inequalities have overlapping shaded regions, and what does that represent?
- How do you handle inequalities involving absolute values?
Tip: Always check whether the inequality involves a strict inequality ( or ) or an inclusive one ( or ), as this affects the type of boundary line!
