  3. 7. the point in a coordinate plane associated with with an ordered pair of real numbers
  4. 8. the second coordinate in an ordered pair of numbers associated with a point in the coordinate plane. Also called y-coordinate.
  5. 10. the abscissa and ordinate of the point, written as an ordered pair of numbers.
  6. 12. 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
  7. 15. a pair of numbers for which the order of the numbers is important(2, -3) is an ordered pair
  8. 17. ax + by = c , where a,b and c are integers and a and b are both not zero.
  9. 18. any equation equivalent to one of the form ax + by = c, where a,b and c are real numbers with a and b not both zero. Its graph is a line.

  1. 1. the equation of a line in the form y = mx + b, where m is the slope and b is the y-intercept.
  2. 2. the y-coordinate of a point where a graph intersects the y-axis.
  3. 5. all the points that are the graphs of the solutions of the equation.
  4. 6. one of the four regions into which the coordinate axes separate the plane
