Terms | Definitions |
|---|---|
 Coefficient | A number that is multiplied by a variable in an equation or expression. In a linear equation of the form y = mx + b, the number m is the coefficient of x as well as the slope of the line. |
| Coordinate pair | A pair of numbers of the form (x, y) that gives the location of a point in the coordinate plane. |
| Function | A relationship between two variables in which the value of one variable depends on the value of the other variable. |
| 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. |
| Origin | The point where the x- and y-axes intersect on a coordinate graph. |
| 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 of a line is the rise divided by the run. |
| X-intercept | The point where a graph crosses the x-axis. What the x coordinate is when the y coordinate is zero. |
| Y-intercept | The point where the graph crosses the y-axis. What the y coordinate is when the x coordinate is zero. |
| Variable | A quantity that can change. |
| Table | A list of values for two or more variables that shows the relationship between them. |
