Across
- 3. of a system the ordered pair that makes all of the equations in a system
- 6. the point where a graph intersects the x-axis, its the value of x when y is equal to zero (x,0)
- 9. solution the system of equations do not intersect at any point resulting in parallel lines
- 11. a symbol or letter representing an unknown quantity
- 12. a numerical or constant factor that is multiplied by a variable in an expression or equation
- 13. the system of equations represent identical lines resulting in an unlimited number of solutions
Down
- 1. a method used to find the solution(s) to a system of equations by solving one equation for one variable and then subtracting that expression into the other equation(s)
- 2. solution when the system of equations intersect at a single point, resulting in exactly one ordered pair
- 4. point where a graph intersects the y-axis, its the value of y when x=zero (o,y)
- 5. lines in a plane that never intersect, no matter how far they are extended in either direction
- 7. a method used to solve a system of equations by elimination one of the variables to obtain a new equation with only one variable
- 8. a method used to solve a system of equations by graphing
- 10. two lines that intersect at a right angle (90 degrees)
