Slope
Rate of change
Use rise over run and the slope formula to compare two points.
Mathematics · Grade 8
See linear relationships as a constant rate of change.
Grade 8 begins with slope, tables, equations and functions. Students learn to recognise what stays constant across different representations of the same linear relationship.
