  1. Alexander BoydChristien Anderson Rate of change and slope

  2. Rate of Change • The ratio of the difference in values of a variable during a time period to the length of that time period

  3. What Is A Positive Slope • If the line is sloping up to the right, the slope is positive (+).

  4. Practice problem #1 Find the slope then graph

  5. Answer

  6. What is A Negative Slope • If the line is sloping down to the right, the slope is negative (-).

  7. Practice problem #2 Find the slope then graph

  8. Answer

  9. What is A Zero Slope • Horizontal lines have a slope of zero and it does not touch the x axis.
