  1. 6. The solution to a system of 2 linear equations.
  2. 7. Where the solution to a system of inequalities occurs.
  3. 9. Slopes of the lines are negative reciprocals of each other. Lines that intersect at a 90 degree angle.
  4. 10. The solution of the system of equations is all real numbers because there is an infinite number of solutions.
  5. 11. A method of solving systems of equations where one variable is replaced with the equivalent expression from the other equation. Gives an exact solution.
Down
  1. 1. 2 or more related inequalities.
  2. 2. 2 or more related equations.
  3. 3. The graph when there is no solution to a system of equations. Lines that never intersect.
  4. 4. The graph when there is one solution to a system of equations.
  5. 5. A method of solving systems of equations where the equations are combined to remove one of the variables. Gives an exact solution.
  6. 8. A method of solving systems of equations where you graph the lines and look for the intersection point.
