| Slope |
|
|
| |
| The slope of a line is defined as the tangent of the angle made by the line with the x-axis in the positive direction (anti-clockwise). |
| |
| If q is the smallest positive angle made by the line with the x-axis, then |
| |
| Slope = tanq = m. |
| |
| The slope of line passing through two points A (x1,y1) and B (x2,y2). |
| |
 |
| |
| From the above figure, |
| |
 |
| |
| (Regardless of the quadrants in which the A and B lie.) |
| |
| Example: |
| |
| Find the slope and the angle of inclination q of the lines through the pairs of points (-7,-3) and (6,10). |
| |
| Suggested answer: |
| |
| Points are (-7,-3) and (6,10). |
