Draw the graph of the line 3x + 4y = 18. With the help of graph find value of y when x = 2. (show this point on the graph)
Answer :
We can draw graph of this line 3x + 4y = 18 , As :
Form a table with different values of x and y :
Now represents these points on x - y plane As :
So we can see that is graph , when x = 2 then y = 3 ( Ans )
We can draw graph of this line 3x + 4y = 18 , As :
Form a table with different values of x and y :
| 3x + 4y = 18 | |
| x | y |
| 0 | 4.5 |
| 1 | 3.75 |
| 2 | 3 |
| 5 | 0.75 |
| 6 | 0 |
| -1 | 5.25 |
| -2 | 6 |
| -6 | 9 |
Now represents these points on x - y plane As :
So we can see that is graph , when x = 2 then y = 3 ( Ans )
