Across
  1. 3. the point at which the line intersects the x-axis at (x,0).17Y-intercept the point at which the line intersects the y-axis at (0,y)
  2. 4. adding or subtracting the equations in the system together so that one of the variables is eliminated, multiplication might be necessary before adding the equations together.
  3. 5. a graph line or boundary is not part of an inequality's solution
  4. 8. the intersection of the half planes of the inequalities; the solution is the set of all points that make all the inequalities in the system true
  5. 11. a region containing all points that has one boundary ,a straight line that continues in both directions infinitely.
  6. 12. a system of equations with at least one ordered pair that satisfies both equations.
  7. 14. a system of equation with no solutions; lines are parallel when graphing.
  8. 15. a system of equations with exactly one solution.
  9. 16. the point at which the line intersects.
Down
  1. 1. solving one of a pair of equations for one of the variables and substituting that into the other equation.
  2. 2. the point at which two lines cross or meet.
  3. 6. solving a system by graphing equations on the same coordinate plane and finding the point of intersection.
  4. 7. rules that allow you to balance, manipulate, and solve equations.
  5. 8. two or more inequalities in the same variables that work together.
  6. 9. a set of equations with the same unknowns.
  7. 10. a graphed line or boundary is part of an inequality's solution.
  8. 13. a system of equations that has an infinite number of solutions, lines coincide when graphed.
