Across 4. The number associated with a particular point on a number line. 6. Like a line. A description of any graph or data that can be modeled by a linear polynomial 7. A visual display of the five number summary. The box-and-whisker plot is a simplified boxplot taught to beginners . It does not show outliers. The whiskers extending all the way to the minimum and maximum values regardless of how far out they may be. 8. The form Y = mx + b of a linear equation in two variables. The slope is m and the y-intercept is b. 9. If (x1, y1) is a point on the line y = mx + b. then y - y1 = m(x - xl) is the point-slope form of the equation 11. The horizontal axis 12. The distance from the origin to the coordinate x. 15. The sum of a set of numbers divided by the number of numbers in the set. 18. The number that occurs most often in a set of numbers. 19. If the value of a depends upon the value of b, or if a is usually defined in terms of b, b is called the independent variable, and it is graphed on the horizontal axis.

Down 1. For each nonzero number a and for each positive integer n, a^-n = 1/a^n. 2. The smallest whole number that can be used as a denominator for two or more fractions. The least common denominator is the least common multiple of the original denominators. 3. Terms that contain identical vari- ables with identical exponents. 5. The vertical axis. 9. Lines that have equal slopes 10. The set of all rational and irrational numbers. 13. A mathematical sentence built from expressions using one or more equal signs (=). 14. Terms which have the same variables and corresponding powers and/or roots. Like terms can be combined using addition an subtraction. Terms that are not like cannot be combined using addition or subtraction. 16. Any of the symbols <, >, ≤, or ≥. 17. A symbol, usually a letter, that represents, and may be replaced by, any number from a particular set of numbers.
