Identify graphs of proportional relationships
Identify graphs of proportional relationships
What you'll learn
- Identify whether a graph represents a proportional relationship by determining if the graph is a straight line through the origin with 80% accuracy.
- Explain, using mathematical vocabulary, why a graph does or does not represent a proportional relationship in at least 2 out of 3 opportunities.
- Apply the concept of the constant of proportionality (k) to determine if a graph shows a proportional relationship by calculating the ratio y/x for at least 3 points on the line and comparing the values.
- Distinguish between graphs that represent proportional relationships and graphs that represent other linear relationships (e.g., y = mx + b where b ≠ 0) with 75% accuracy.
