  2. 4. a way to display frequencies or relative frequencies for two categorical variables.
  3. 5. A system of equations that have infinite solutions.
  4. 6. a number that describes both the direction and the steepness of the line.
  5. 9. a system of equations if there is no solution because the lines are parallel.
