| Parallel lines | Lines in the same plane with the same slope that do not intersect |
| Perpendicular lines | Two line that intersect to form right angles |
| Dependent variable | The output for a function - graphed on the y-axis |
| Independent variable | The input for a function - graphed on the x-axis |
| Negative (opposite) recipricals | Slopes of perpendicular lines |
| Equal or the same | Slopes of parallel line |
| Slope | Numberical value that tells how steep a line is - also rise over run |
| Vertical line | An up and down line |
| Horizontal line | A left and right line |
| x-intercept | Place where a line crosses the x-axis |
| y-intercept | Place where a line crosses the y-axis |
| y=mx+b | Slope-intercept form of a linear equation |
