  1. 2. The process of finding an equation that best fits the data collected.
  2. 4. line. The general form is f(x) = mx + b where m represents the slope (rate of change) and b represents the y-intercept.
  3. 5. Formula that describes a sequence or series of numbers.
  4. 7. Measure of the linear association between two variables. It can range from – 1 (perfect negative relationship) to 1 (perfect positive relationship). The correlation coefficient will be 0.8 or better for a good fit. If the association is other than

  2. 3. Repeat the sum a specified number of times for the expression changing the variable by 1.
  3. 6. A sequence made by adding the same value each time.
  4. 8. this relationship is described by the coefficient of determination.
