Across
  1. 2. the point where a graph intersects the x-axis, its value of x when y is equal to zero (x,0)
  2. 3. the point where a graph intersects the y-axis, it is the value of y when x is equal to zero (0,y)
  3. 6. a numerical or constant factor that is multiplied by a variable in an expression or equation
  4. 10. the ordered pair that makes all of the equations in a system true
  5. 12. the system of equations intersect at a single point, resulting in exactly one ordered pair that satisfies all of the systems of equations, the lines will have different slopes
  6. 13. used to find the solutions to a system of equations by solving one equation for one variable then substituting that expression into the other equations
  7. 14. two or more linear equations that are solved simultaneously to find the values of the variables that satisfy all the equations in the system
Down
  1. 1. two lines that intersects at a right angle (90 degrees)
  2. 4. used to solve a system of equations by eliminating one of the variables to obtain a new equation with only one variable
  3. 5. the system of equations represent identical lines resulting in an unlimited number of solutions, the lines will have the same slope and y-intercept
  4. 7. 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 different slopes
  5. 8. lines in a plane that never intersect, no matter how far they are extended in either direction
  6. 9. used to solve a system of equations by graphing each equation on the coordinate plane and identifying the points where the graphs intersect if they intersect these points of intersection represents the solutions to the system of equation
  7. 11. a symbol or letter representing an unknown quantity
