Across
  1. 1. two lines that intersect at a right angle(90 degrees)
  2. 3. the point where graph intersects the y-axis.It is the value of y when x is equal to zero(0,y)
  3. 4. the point where a graph intersects the x-axis.It is the value of x when y is equal to zero(x,0)
  4. 7. used to solve a system of equations by eliminating one of the variables to obtain a new equation with only one variable
  5. 10. the system ofequations 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
  6. 11. a numerical or constant factor that is multiplied by a variable in an expression or equation
  7. 13. a symbol or letter representing an unknown quantity
Down
  1. 1. lines in a plane that never intersect, no matter how far they are extended in either direction
  2. 2. two or more linear equations that are solved simultaneously to find the value of the variables that satisfy all the equations in the system
  3. 5. the ordered pair that makes all of the equations in a system true
  4. 6. used to find the solutions to a system of equations by solving one equation for one variable and then substituting that expression into the other equations
  5. 8. the system of equations don't 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
  6. 9. the system of equations represent identical lines resulting in an unlimited number of solutions;the lines will have the same slope and y-intercept
  7. 12. used to solve a system of equations by graphing each equations on the coordinate plane and identifying the points where the graphs intersect,if they intersect;They points of intersection represent the solutions to the system of equations
