| Horizontal Axis | X - axis |
| Origin | Point (0,0) |
| Veritcal Axis | Y - axis |
| Abscissa | x- coordinate |

| Linear Equation | an equation whose graph is a line |
| Standard Form of a Linear Equation | ax + by = c |
| Slope | ( change in y)/(change in x) |
| Positive Slope | line rises form left to right |
| Negitive Slope | line falls left to right |
| Horizontal Line | has slope of zero |
| Vertical Line | slope is undefined |
| Collinear Points | points that lie on the same line |
