  1. 3. the horizontal number line in a coordinate plane. Also called the x-axis.
  2. 6. the first coordinate in an ordered pair of real numbers associated with a point in a coordinate plane. Also called the x-coordinate.
  3. 8. the y-coordinate of a point where a graph intersects the y-axis.
  4. 9. the point in a coordinate plane associated with with an ordered pair of real numbers
  5. 11. the horizontal axis in a coordinate plane.
  6. 12. the second coordinate in an ordered pair of numbers associated with a point in the coordinate plane. Also called y-coordinate.
  7. 13. the vertical number line in a coordinate plane.
  8. 14. a pair of numbers for which the order of the numbers is important(2, -3) is an ordered pair
  9. 15. the vertical number line in a coordinate plane.
  10. 18. an ordered pair of numbers that make the sentence true
  11. 20. one of the four regions into which the coordinate axes separate the plane
  12. 21. all the points that are the graphs of the solutions of the equation.
  13. 23. the x-coordinate of a point where a graph intersects the x-axis.
  14. 24. If (x1, y1) and (x2, y2) are two different points on a line, the slope of the line is given by y2- y1 / x2-x1. A horizontal line has a slope of 0; a vertical line has no slope
  15. 25. the x- and y-axis in the coordinate plane.
