3. The horizontal line running through the origin on a coordinate plane.
6. deviation The square root of the variance.
8. An expression that is used to compute a value.
10. The study of mathematical symbols and the rules for manipulating those symbols.
11. like terms Using the distributive law to add any two multiples of an expression such as x. For example, you can simplify 4x+5x into 9x.
13. a quantity representing the power to which a given number or expression is to be raised, usually expressed as a raised symbol beside the number or expression.
15. A point on a 2-dimensional plane is described by a pair (x,y). The coordinate x is given by the labels below the grid, and the coordinate y is given by the labels to the left of the grid.

1. The vertical line running through the origin on a coordinate plane.
2. An expression or equation in which the highest power of a variable has exponent 2.
4. A number that is raised to a power.
5. root A square root of a is a number b whose square is a. That is, b2=a. If b is a square root of a, then so is −b. If a≥0, “the” square root of a, written √a, is the square root of a that is positive or zero.
7. The distance between two quantities, or the answer to a subtraction problem.
9. value The distance a number is from 0.
12. A single fixed number (unlike a variable, whose value can vary).
