Constant rate of change

What you'll learn

  • Identify the constant rate of change (slope) from a table of values representing a linear relationship with at least 80% accuracy.
  • Calculate the constant rate of change (slope) from a graph of a linear relationship, given two distinct points on the line, with 75% accuracy.
  • Explain, in writing, how the constant rate of change (slope) affects the steepness and direction of a line on a graph, using appropriate mathematical vocabulary.
  • Solve real-world problems involving constant rate of change (slope), such as calculating speed or unit price, and show all work to justify the solution.
