The equation of this graph is
-
- y = – x
- y = – 3x
- y = x
- y = 3x
Correct Option: D
Given Here , y1 = 6 , y2 = -3 , x1 = 2 and x2 = -1
We know that ,
The equation of two points on given line is
| ( y - y1 ) = | ( x - x1 ) | |
| x2 - x1 |
| ( y - 6 ) = | ( x - 2 ) | |
| -1 - 2 |
| ( y - 6 ) = | ( x - 2 ) | |
| 3 |
⇒ y - 6 = 3( x - 2 ) ⇒ y = 3x
Hence , required equation is y = 3x .
