Across
- 5. lines in a place that never intersect, no matter how far they are extended in either direction
- 7. the system of equations do not interest 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.
- 9. the system of equations intersects at a single point, resulting in exactly one ordered that satisfies all of the equations in the system; the lines will have different slopes
- 11. used to solve a system of equations by eliminating one of the variables to obtain a new equation with only one variable
- 13. 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 represent the solutions to the solutions to the system of equations.
- 14. lines in a plane that never intersect at a right angle (90 degrees)
Down
- 1. a numerical or constant factor that is multiplied by a variable in an expression or equation
- 2. used to find the solution to a system of equations by solving one equation for one variable and then substituting that expression into the other equations
- 3. A System the ordered pair that makes all of the equations in a system true
- 4. the system of equations represent identical lines resulting in an unlimited number of solutions; the lines will have the same slope and y-intercept
- 6. Equations two or more linear equations that are solved simultaneously to find the values of the variables that satisfy all equations in the system
- 8. the point where a graph intersects the y axis. It is the value of y when x is equal to zero (0,y)
- 10. a symbol or letter representing an unknown quantity
- 12. the point where a graph intersects the x- axis. It is the value of x when y is equal to zero
