| coefficient | A number that is multiplied by a variable in an equation or expression. |
| constant rate of change | When the y value continues to change in a constant amount (like 3,6,9,12). This is a linear relationship and would create a straight line if graphed. |
| constant term | A number in an equation that is not multiplied by a variable or an amount added to or subtracted from the term involving variables. |
| equation of a line | A straight line on a coordinate plane can be described by the equation y = mx + b where m is the slope of the line and b is the intercept. |
| linear relationship | A relationship in which there is a constant rate of change between two variables; for each unit increase in one variable, there is a constant change in the other variable. |
| patterns of change | If the table values, especially y, change in a pattern, it may not be linear and not result in a straight line if graphed. |
| Properties of Equality | For all real numbers, a, b, and c: Addition: If a = b, then a + c = b + c; Subtraction: If a = b, then a - c = b - c; Multiplication: If a = b, then a * c = b * c; Division: If a = b and c is not equal to 0, then a/c = b/c. |
| rise | The vertical change between two points on a graph. |
| run | The horizontal change between two points on a graph. |
| slope | The number that expresses the steepness of a line. The slope is the ratio of the vertical change to the horizaontal change between any two points on the line. |
| solving an equation | Find what values fultill a condition stated as an equation. |
| y-intercept | The point where the graph crosses the y-axis. |
