Chapter 12.2
Understanding graphs of linear relationships
What You'll Learn
Read and interpret coordinates on linear graphs to extract meaningful data
Identify patterns and relationships between variables on a graph
Create tables of values from graph points to organize information
Calculate values using linear relationships and equations like y = mx + b
Determine when it's reasonable to use points between data values
What You'll Practice
1
Extracting information from cost versus quantity graphs
2
Finding speed using distance and time from graph coordinates
3
Creating tables of values from plotted points
4
Using linear equations to predict values beyond the graph
Why This Matters
Understanding graphs of linear relationships lets you analyze real-world data like costs, distances, and rates. You'll use these skills in science labs, economics, and everyday situations like comparing prices or planning travel times.
