Across
  1. 2. of Equations When more than one equation is graphed on the coordinate plane. Can have ONE, NO or INFINITELY MANY solutions
  2. 6. Slope A line falls from left to right
  3. 7. The x-coordinate of the point where the line crosses the x-axis
  4. 9. Sequence A sequence in which you get the next consecutive term by adding or subtracting a constant value. In other words, we just add or subtract the same value over and over...infinitely
  5. 15. Slope Vertical line
  6. 17. How far left to how far right your graph goes (x value behavior)
  7. 18. Formula Helps us to find ANY term in an Arithmetic Sequence
  8. 19. The y-coordinate of the point where the line crosses the y-axis
  9. 20. A mathematical sentence that contains an equals sign
  10. 21. Slope Horizontal line
  11. 23. A statement that compares two quantities using <, >, ≤,≥, or ≠
  12. 25. Function A function whose graph is a straight line
Down
  1. 1. Slope A line that rises from left to right
  2. 3. The steepness of a line on a graph; rise over run; change in y over the change in x
  3. 4. How far down to how far up your graph goes (y value behavior)
  4. 5. When there is only one output (y) for every input (x)
  5. 8. Many Solutions of a System of Equations When two lines touch at every point. The lines are the same.
  6. 10. Formula Helps us to find the NEXT term in an Arithmetic Sequence
  7. 11. Difference The constant value that is being added or subtracted to get the next number in an Arithmetic Sequence
  8. 12. "Golden Rule" of Inequalities Whenever you multiply or divide both sides of an inequality by a negative number, you must flip the inequality symbol.
  9. 13. Notation An equation in the form of 'f(x)=' to show the output value of a function, f, for an input value x
  10. 14. inequality Can be formed by replacing the equal sign in a linear equation with an inequality symbol
  11. 16. Equations An equation with more than one variable
  12. 22. Solution of a System of Equations When two lines with different slopes intersect at only one point
  13. 24. Solution of a System of Equations When two lines do not cross or touch at any point. The lines are parallel.
