| 286485047 | Positive Slope | A line that goes up from left to right. | |
| 286485048 | Negative Slope | A line that goes down from left to right. | |
| 286485049 | Undefined Slope | A vertical line, or two points where the difference of the x values is zero. | |
| 286485050 | Zero Slope | A horizontal line, or two points where the difference of the y values is zero. | |
| 286485051 | Point Slope Formula | A formula which gives us the slope for two points. Ex. (y2-y1)/(x2-X1) | |
| 286485052 | Parallel Lines | Lines that have the same slope. | |
| 286485053 | Perpendicular Lines | Lines whose slopes are negative reciprocals (Ex: m= 3, m= (-1/3) Lines which form a 90 degree angle. | |
| 286485054 | Y-Intercept | Where the line crosses the y-axis. | |
| 286485055 | X-Intercept | Where the line crosses the x-axis. | |
| 286485056 | Finding X-Intercept | To find the x-intercept we substitute zero for y. | |
| 286485057 | Standard Form | Ax + By = C | |
| 286485058 | Slope-Intercept Form | Y = mX + B | |
| 286485059 | Slope and a Point Method | Given: Slope: (m= 1/2) Point: (1,2) First: Plot the point! Second: Use the top number of slope to move up (rise), and the bottom number of slope (run) to move left or right |
