| Equation of a line in Intercept form |
|
| |
| |
 |
| |
| Let AB be a line making intercepts OA = a on x-axis and OB = b on y-axis. |
| |
| The coordinates of A = (a, 0) and the coordinates of B = (0,b). |
| |
| Let P(x,y) be any point on AB. Since APB are collinear, |
| |
| Slope of AP = Slope of AB |

| |
| Dividing by ab throughout, we get |
