Across
- 2. with only one variable 12.Substitution Method: used to find the solution(s) to a system of equations by solving one equation for one variable and then substituting that expression into the other equation(s)
- 7. Lines: two lines that intersect at a right angle (90 degrees)
- 9. of a System: the ordered pair that makes all of the equations in a system true
- 11. a symbol or letter representing an unknown quantity
- 12. 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
- 13. the point where a graph intersects the x-axis. It is the value Of x when y is equal to zero (x, O)
- 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; the lines will have different slopes
- 15. the point where a graph intersects the
- 16. of Equations: 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. Solutions: the system of equations represent identical lines resulting in an unlimited number of
- 3. Lines: lines in a plane that never intersect, no matter how far they are extended in either direction
- 4. by a variable in an expression or equation
- 5. Method: used to solve a system of equations by graphing each equation on the coordinate plane and identifying the point(s) where the graphs intersect, if they intersect; These points of intersection represent the solutions to the system of equations
- 6. a numerical or constant factor that is
- 8. Method: used to solve a system of equations by eliminating one of the variables to obtain a new equation with only one variable
- 10. Method: used to find the solution(s) to a system of equations by solving one equation for one variable and then substituting that expression into the other equation(
