  1. 4. The point of intersection for a system of equations.
  2. 6. An equation that when graphed will form a line.
  3. 9. Two lines cross at a point called an intersection.
  4. 11. Method Method of solving a system in which two equations are added together in a manner that will eliminate one of the two variables.
  5. 12. The number that is multiplied by the variable; 3x has a coefficient of 3.

  1. 1. A method for solving a system of linear equations in which the equivalent expression of a variable is substituted for that variable into the other equation.
  2. 2. Two lines that are co-planar and intersect to form four right angles are called perpendicular lines.
  3. 3. A type of system that has a solution.
  4. 5. A type of system that does not have a solution.
  5. 7. An inequality that when graphed will form a line that divides the coordinate plane into a shaded region and unshaded region.
  6. 8. Two lines that are co-planar and never intersect are called parallel lines.
  7. 10. The rate at which the y value of a linear function rises or falls as x increases.
