Across
- 4. shows all the solutions of the inequality on a number line.
- 8. the number lines intersect at the origin
- 9. are less than 0. They are written with a negative sign
- 12. the set of all solutions of an inequality is called the solution set
- 13. are greater than 0. They can be written with or without a positive sign
Down
- 1. two numbers that are the same distance from 0 on a number line, but on opposite sides of 0
- 2. separate the coordinate plane into four regions called quadrants
- 3. is a number that can be written as a/b, where a and b are integers and b = 0
- 5. of a number is the distance between the number and 0 on a number line. The absolute value of a number a is written as |a|
- 6. is formed by the intersection of a horizontal number line and a vertical number line.
- 7. is a mathematical sentence that compares expressions
