7. a pair of elements a, b having the property that ( a, b) = (u, v ) if and only if a = u, b = v.
9. the set of all possible inputs for the function
10. a horizontal number line
12. the area contained by the x and y axes
13. The picture obtained by plotting all the points of an equation or inequality
17. the difference between the largest and smallest data points in a set of numerical data.
19. A value or values which, when substituted for a variable in an equation, make the equation true.
20. a way of writing the number in a form that follows certain rules
21. the line of figures or data arranged from top to bottom at the side of the graph.
23. a variable (often denoted by x ) whose variation does not depend on that of another
24. the number in an ordered pair of numbers (as x in (x, y)) that gives the location of a point along the x-axis. called also x-coordinate.
25. the numbers without fractions and it is a collection of positive integers and zero

1. the second element in an ordered pair.
2. used to represent the position of a point on the coordinate plane with respect to the origin
3. is a two-dimension surface formed by two number lines
4. One of the lines in the coordinate system that represents one of the dimensions.
6. the starting point
8. is a vertical number line
11. the variable that changes as a result of the independent variable manipulation
14. the principal or horizontal axis of a system of coordinates, points along which have a value of zero for all other coordinates.
15. a pair of numbers which are used to determine the position of a point or a shape in a 2-dimensional plane.
16. the first element in an ordered pair
18. is an algebraic equation of the form y=mx+b. involving only a constant and a first-order (linear) term, where m is the slope and b is the y-intercept
22. the distance along the y-axis
