"For a linear equation in one variable, determine the conditions under which the equation has no solution, a unique solution, or infinitely many solutions."

What you'll learn

  1. Determine whether a linear equation in one variable has exactly one solution, no solution or infinitely many, by simplifying both sides and then comparing coefficients and constants
  2. Explain why a vanished variable leaves a statement that determines the case
  3. Find the values of a parameter for which an equation has no solution, infinitely many solutions or exactly one
  4. Describe each case as a configuration of two lines
