5. of a system the ordered pair that makes all of the equations in a system true
9. a symbol or letter representing an unknown quantity
10. of equations two or more linear equations that are solved simultaneous find the of the variables that satisfy all the equations in the system
11. lines two lines that intersect at a right angle (90 degrees)
12. solutions the system of equations represents identical lines resulting in an unlimited number of solutions the lines will have the same slope and y-intercept
13. solutions the system of equations do not intersects at any point resulting in parallel lines there are no values that satisfy the system of equatins the lines will have the same slope but different y-intercept

1. the point where a graph intersects the x-axis it is the value of x when y is equal to zero(x,0)
2. the point where a graph intersects the y-axis it is the value of y when x is equal to zero(0,y)
3. a numerical or constant factor that is multiplied by variable in an expression or equation
4. lines lines in a plane that never intersect no matter how far they intersecting in either direction
6. 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. method 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 system of equations
8. method used to solve a system of equations by elimination one of the variables to obtain a new equation with only one variable
