Solution:
Given pair of linear equations which represents the paths of train A and train B,
3x + 4y – 12 = 0………………………….. (i)
6x + 8y – 48 = 0 ………………………….. (ii)
To represent these equations graphically, we need at least two solutions for each (i) and (ii).
And let’s put them on a table for each.
For equation (i),
For equation (i),
The above can be plotted in a graph as below:
