Question
**Communicate Mathematics**  
- Explain the slope of a line. Ben chose two points on the line to find the slope. Phoebe used two different points to find the slope. Did they get the same answer? Explain.

**Analyze Relationships**  
- Two lines pass through the origin. The lines have slopes that are opposites. Compare and contrast the lines.

**Instructor's Notes:**
- When analyzing the lines that pass through the origin with opposite slopes, remember that if line 1 has a slope of \( m \), line 2 will have a slope of \( -m \).
- Consider how the orientation of the lines in the coordinate plane differs due to their opposite slopes.
- Use diagrams or graphs to visually represent the lines and observe their symmetrical arrangement relative to each axis.
