  1. 3. method-used to solve a systems of equations by elimination one of the variables to obtain a new equation with one variable
  2. 6. method-used to find the solution to a system of equations by solving one equation for one variable and then substituting that expression into other equations
  3. 7. point where graph intersects the y-axis it is the value of y when x is equal to zero
  4. 10. point where graph intersects the x-axis it is the value of x when y is equal to zero
  5. 12. of a equation-two or more linear equations that are solved simultaneously to find the values of the variables that satisfy all equations in a system true
  6. 13. of a system-the order pair that makes all of the equations in a system true solutions the line will have the same slope and y-intercept
  7. 14. solution-the system of equations intersect at a single point resulting in exactly one ordered pair that satisfies all of the equations in the system that lines will have different slopes

  1. 1. method-used to solve a system of equations by graphing each equation on the coordinate plane and identifying the point where the graph intersects if they intersect these points intersection represents the solutions to the system of equations
  2. 2. numerical or constant factor that is multiplied by a variable
  3. 4. symbol or letter representing an unknown quantity
  4. 5. solutions-the system of equations represented by identical lines resulting in a unlimited number of solutions the line will have the same slope and y-intercept
  5. 8. solutions-the system of equations do not intersect at any point resulting in parallel line there are no values that satisfy the system of equations the lines will have the same slope but different y-intercepts
  6. 9. lines-two lines that intersect at a right angle 90 degrees
  7. 11. lines-lines in a plane that never intersect no matter how far apart they are extended in either direction
