and route of train B is given by the equation 
. Represent the route of train A and B graphically.
Solution- Given, linear equations represents the routes of train A and train B,
………………………….. (i)
………………………….. (ii)
Represent these equations graphically, we need at least two solutions for equation (i) and (ii).
And let’s put them in a table for each:
From equation (i),
| x |  |
