A point R(h, k) divides a line segment between the axis in the ratio 1 : 2 what will be the equation of line ?
-
-
x - 2y = 4 h k -
x + 2y = 3 h k -
x + y = 1 k h -
x + y = 1 2k h
-
Correct Option: B
Using internal section formula, we have
| h = | ||
| 1 + 2 |
⇒a = 3h
Similarly,
| k = | ||
| 1 + 2 |
| k = | ||
| 3 |
| b = | |
| 2 |
∴ Equation of line be
| + | = 1 | |||
| a | b |
| ⇒ | + | = 1 | ||
| 3h | 3k |
| ⇒ | + | = 3 | ||
| h | k |
