| Slope | A number that describes how fast a graph increases or decreases. |
| Slope | Another word for rate of change. |
| Slope | A number that describes the steepness of a line. |
| Positive | A line that rises from left to right has a(n) ____ slope. |
| Negative | A line that falls from left to right has a(n) ____ slope. |
| Zero | A line that is horizontal has a(n) ____ slope. |
| Undefined | A line that is vertical has a(n) ____ slope. |
| Horizontal | Runs left to right. |
| Vertical | Runs up and down. |
| Rate of Change | A ratio comparing change in y-values to change in x values. |
| Slope | "Rise over run" or "change in y over change in x". |
| y = mx + b | The slope intercept form of a line. |
| y-intercept | The point where the graph of a function crosses the y-axis |
| x-intercept | The point where the graph of a function crosses the x-axis |
| Absolute value | The distance from a number to zero is called the its ____. |
| Translate Up | Increasing b in y = mx + b causes the graph to ____. |
| Translate Down | Decreasing b in y = mx + b causes the graph to ____. |
| Become Steeper | Increasing m in y = mx + b causes the graph to ____. |
| Become Less Steep | Decreasing m in y = mx + b causes the graph to ____. |
| The Same | The slopes of parallel lines are ____. |
| Negative Reciprocals | The slopes of perpendicular lines are ____. |
| Parallel | Lines that lie in the same plane and never cross. |
| Perpendicular | Lines that intersect to form right angles. |
| Standard Form of a Linear Equation | Ax + By = C |
| Slope Intercept Form of a Linear Equation | y = mx + b |
| Process for finding y-intercept | Substitute 0 for x in equation then solve or y. |
| Process for finding x-intercept | Substitute 0 for y in equation then solve for x. |
| (x, 0) | The coordinate for the x-intercept. |
| (0, y) | The coordinate for the y-intercept. |
| If the rate of change is changed then ____ | The slope is increased or decreased. |
| If the initial condition is changed then ____ | The y-intercept is changed. |
| < | is less than |
| > | is greater than |
| System of Equations | Two or more equations with two or more unknowns. |
| One | In a system of equations if the lines intersect then there is(are) ___ solutions. |
| No | In a system of equations if the lines are parallel then there is(are) ___ solutions. |
| Many | In a system of equations if the lines are the same (intersect at every point) then there is(are) ___ solutions. |
