| Scatter Plot | A graph that shows the “general” relationship between two sets of data. For each point that is being plotted there are two separate pieces of data. |
| Simple Event | When an event consists of a single outcome (e.g., rolling a number cube). |
| Simplest Form (of an Expression) | When all like terms are combined (e.g., 8x + 2(6x – 22) becomes 20x – 44 when in simplest form). |
| Simplify | To write an expression in its simplest form (i.e., remove any unnecessary terms, usually by combining several or many terms into fewer terms or by cancelling terms). |
| Slope (of a Line) | A rate of change. The measurement of the steepness, incline, or grade of a line from left to right. It is the ratio of vertical change to horizontal change. |
| Slope-Intercept Form | An equation of a straight, non-vertical line written in the form y = mx + b, where m is the slope and b is the y-intercept. |
| Square Root | One of two equal factors (roots) of a number or expression; a radical expression ( a ) with an understood degree of 2. |
| Standard Form (of a Linear Equation) | An equation of a straight line written in the form Ax + By = C, where A, B, and C are real numbers and where A and B are not both zero. |
| Stem-and-Leaf Plot | A visual way to display the shape of a distribution that shows groups of data arranged by place value; a way to show the frequency with which certain classes of data occur. The |
| Substitution | The replacement of a term or variable in an expression or equation by another that has the same value in order to simplify or evaluate the expression or equation. |
| System of Linear Equations | A set of two or more linear equations with the same variables. The solution to a system of linear equations may be found by linear combination, substitution, or graphing. |
| System of Linear Inequalities | Two or more linear inequalities with the same variables. |
| Systems of Equations | A set of two or more equations containing a set of common variables. |
| Term | A part of an algebraic expression. |
| Terminating Decimal | A decimal with a finite number of digits. A decimal for which the division operation results in either repeating zeroes or repeating nines |
| Trinomial | A polynomial with three unlike terms (e.g., 7a + 4b + 9c). |
| Unit Rate | A rate in which the second (independent) quantity of the ratio is 1 |
| Variable | A letter or symbol used to represent any one of a given set of numbers or other objects |
| Whole Number | A natural number or zero. |
| x-Axis | The horizontal number line on a coordinate plane that intersects with a vertical number line |
| x-Intercept(s) | The x-coordinate(s) of the point(s) at which the graph of an equation crosses the x-axis |
| y-Axis | The vertical number line on a coordinate plane that intersects with a horizontal number line |
| y-Intercept(s) | The y-coordinate(s) of the point(s) at which the graph of an equation crosses the y- axis |
