🔢 Grade 8 • 📈 Linear Relationships and Slope

Linear Relationships and Slope

Interpret slope as rate of change, identify initial value, and compare linear models from tables, graphs, equations, and real contexts.

📋 What You'll Learn

  1. 1 Interpret slope as a rate of change in real situations
  2. 2 Identify slope and y-intercept from graphs, tables, equations, and verbal descriptions
  3. 3 Compare proportional and non-proportional linear relationships
  4. 4 Model real situations with linear equations and graphs
