Across
  1. 2. point where a graph intersects the y-axis. It is the value of y when x is equal to zero (0, y)
  2. 6. of Equations-two or more linear equations that are solved simultaneously to find the values of the variables that satisfy all the equations in the system
  3. 8. Method-used to solve a system of equations by graphing each equation on the coordinate plane and identifying the point(s) where the graph intersect, if they intersect; These points of intersection represent the solutions to the system of equations
  4. 9. Solutions-the system of equations represent identical lines resulting in an unlimited number of solutions; the lines will have the same slope and y-intercept
  5. 10. Method-used to find the solutions(s) to a system of equations by solving one equation for one variable and then substituting that expression into the other equation(s)
  6. 12. 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; the lines will have different slopes
  7. 13. numerical or constant factor that is multiplied by a variable in an expression or equation
Down
  1. 1. point where a graph intersects the x-axis. It is the value of x when y is equal to zero (x, 0)
  2. 3. Method-used to find the solutions(s) to a system of equations by solving one equation for one variable and then substituting that expression into the other equation(s)
  3. 4. symbol or letter representing an unknown quantity
  4. 5. Lines-two lines that intersect at a right angle (90 degrees)
  5. 6. of a system-the ordered pair that makes all of the equations in a system true
  6. 7. Lines-lines in a plane that never intersect, no matter how far they are extended in either direction
  7. 11. Solutions-the system of equations do not intersect at any point resulting in parallel lines; there are no values that satisfy the system of equations; the lines will have the same slope but different y-intercepts
