Explore Learning
1. Direct Variation: Adjust the constant of variation and explore how the graph of the direct variation function changes in response.
2. Direct and Inverse Variation: Adjust the constant of variation and explore how the graph of the direct or inverse variation function changes in response. Compare direct variation functions to inverse variation functions.
