[ m = \fracy_2 - y_1x_2 - x_1 ] Where $m$ represents the slope, and $(x_1, y_1)$ and $(x_2, y_2)$ are any two distinct points on the line.
If the problem involves a graph with labels (like "Time" and "Distance"), make sure your rate of change includes units (e.g., "5 meters per second"). Summary for Success 3-3 Skills Practice Rate Of Change And Slope Answer Key
