Graphing Proportional Relationships
Plotting pairs of values from ratio tables on the coordinate plane to visualize proportional relationships.
Key Questions
- Predict what the steepness of a line on a ratio graph tells us about the relationship.
- Construct a graph from a ratio table and interpret its meaning.
- Analyze how the origin (0,0) relates to proportional relationships on a graph.
