Linear Relationships: Slope, Equations, and Meaning
A practice set for 8th graders reviewing proportional and non-proportional linear relationships. Students find slope, write the equation of a graphed line, and interpret the slope and y-intercept in real-world contexts, with a worked example and key ideas to anchor the work.
“Create a review of proportional and non-proportional linear relationships. This should focus on finding the slope, the equation that represents the line graphed, and interpreting the meaning of the slope and the y-intercept in the context of the problem.”
Teacher Guide & Tips
- Use as a 45-minute review block after students have seen y = mx + b, either whole-class with the key ideas projected or in pairs.
- Discussion question: If a table has y = 0 when x = 0, what does that tell you about the line, and why does that make the relationship proportional?
- Scaffold for struggling readers: have them first complete the table check at x = 0 and label the y-intercept before attempting the full equation.
- Extension for advanced students: ask them to explain what the slope and y-intercept would mean for a context where the intercept is negative, such as a starting debt.
- Estimated time: about 30 to 45 minutes for the full set, with extra time if students need to revisit the worked example.
