1. Integers less than 0 are (positive, negative) integers

2. Two numbers represented by points that are the same distance from 0 are (opposites, integers).

3. The absolute value of 7 is (7, -7).

4. The opposite of (12, -12) is -12.

5. The (coordinate system, origin) is the point where the horizontal and vertical number lines intersect.

6. The horizontal number line is called the (x-axis, y-axis).

7. In an (ordered pair, coordinate pair), the first number is the x- coordinate and the second number is the y-coordinate.

8. In mathematics, a (quadrant, coordinate plane) is used to graph points in a plane.

9. Whole numbers and their opposites are referred to as (integers, fractions)

10. Two integers that are opposites are called (algebra pairs, additive inverses)

11. The x-axis and the y-axis separate the plane into four (quadrants, coordinates).

12. The first number in an ordered pair is the (x-coordinate, y coordinate).

13. The second number in an ordered pair is the (x-coordinate, y- coordinate).

14. The sum of two (positive, negative) integers is negative.

15. The sum of any number and its additive inverse is (zero, positive).
