Math Problem Statement
Solution
The graph shows two lines representing (blue line) and (red line). We are tasked with solving the inequality using the graph.
Step-by-step process:
- Intersection Point: The blue line () and red line () intersect at the point .
- Behavior of the lines:
- To the left of , the blue line () is above the red line (). Therefore, in this region.
- To the right of , the blue line () is below the red line (). Therefore, in this region.
Solution:
The inequality holds for . Therefore, the solution is:
Would you like any further explanation or details? Here are five related questions for further practice:
- How do you find the equation of the lines from the graph?
- How would the solution change if the inequality was ?
- What is the meaning of the intersection point in terms of ?
- How can you determine if in a certain interval using only the graph?
- How would you solve the inequality if the lines were curved (non-linear)?
Tip:
When solving inequalities with graphs, always check where the curves or lines intersect, as this is where the sign of the inequality changes.
