  1. 5. a variable whose variation does not depend on that of another.
  2. 6. are lines in a plane that are always the same distance apart
  3. 11. No matter what constant is substituted in for the variable, the equation is ALWAYS true.
  4. 13. When two or more lines cross each other in a plane
  5. 14. variable, In algebra, a symbol (usually a letter) standing in for an unknown numerical value in an equation
Down
  1. 1. The number before the variable
  2. 2. All points in common
  3. 3. Taking away something
  4. 4. You couldn't possibly list all the solutions for an equation, because there are infinite limitless or endless in space
  5. 7. Substitution means putting numbers in place of letters to calculate the value of an expression .
  6. 8. a variable whose value depends on that of another.
  7. 9. There is no answer to the equation. It is impossible for the equation to be true no matter what value we assign to the variable.
  8. 10. Its value is constantly the same.
  9. 12. Is where you actually eliminate one of the variables by adding the two equations.
