Questions & Step-by-Step Solutions

Which of the following describes a dependent system of linear equations?
  • Step 1: Understand what a system of linear equations is. It is a set of two or more equations with the same variables.
  • Step 2: Know that a dependent system means the equations are not independent; they are related.
  • Step 3: Realize that if two equations represent the same line, they will have the same slope and y-intercept.
  • Step 4: Recognize that if the equations are the same line, they will have infinitely many solutions because every point on the line is a solution.
  • Step 5: Conclude that a dependent system of linear equations is one where the equations represent the same line, leading to infinitely many solutions.
