3. the first coordinate in an ordered pair of real numbers associated with a point in a coordinate plane. Also called the x-coordinate.
6. locate the graph of an ordered pair of real numbers in a coordinate plane.
10. 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.
11. the first coordinate in an ordered pair of real numbers associated with a point in a coordinate plane. Also called the x-coordinate.
13. the second coordinate in an ordered pair of numbers associated with a point in the coordinate plane. Also called y-coordinate.
14. an ordered pair of numbers that make the sentence true
17. all the points that are the graphs of the solutions of the equation.
18. lines in the same plane that do not intersect; nonvertical lines that have the same slope.
20. the set consisting of zero and all the positive integers.
21. the vertical number line in a coordinate plane.
22. one of the four regions into which the coordinate axes separate the plane
24. a pair of numbers for which the order of the numbers is important(2, -3) is an ordered pair
25. a plane in which an ordered pair can be located by reference to two intersecting number lines.
27. the x- and y-axis in the coordinate plane.

1. the y-coordinate of a point where a graph intersects the y-axis.
2. ax + by = c , where a,b and c are integers and a and b are both not zero.
4. the equation of a line in the form y = mx + b, where m is the slope and b is the y-intercept.
5. the x-coordinate of a point where a graph intersects the x-axis.
7. the zero point on a number line. The intersection of the axes on a coordinate plane.
8. the point in a coordinate plane associated with with an ordered pair of real numbers
9. the abscissa and ordinate of the point, written as an ordered pair of numbers.
12. the horizontal number line in a coordinate plane. Also called the x-axis.
15. 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
16. the vertical number line in a coordinate plane.
19. the second coordinate in an ordered pair of numbers associated with a point in the coordinate plane. Also called y-coordinate.
23. points that lie on the same line
26. the horizontal axis in a coordinate plane.
