When does the graph pass through the origin?
Answer :
Whenever we are having our linear equation with no constant term , For example :
y = 2x , y + 3x = 0
Then we get graph of our linear equation passing through origin :
As , we form table for different values of x and y both equation , As :
Now we draw these points on x - y plane and get our graph for both equations , As :
From graph we can see both equation are passing through origin .

| x | y | x | y |
| 0 | 0 | 0 | 0 |
| 1 | 2 | 1 | - 3 |
| 2 | 4 | 2 | - 6 |
| - 1 | - 2 | -1 | 3 |
