A maths teacher and a student went for competition by the train. The teacher told his student that the path of train A is given by the equation \(6x + 8y – 48 = 0\) and path of train B is given by the equation \(3x+4y-12=0\). The teacher asked some questions to his student to test his math knowledge.
 
Based on the above situation try to answer for the following question.
 
1. The system of equations has 
 
2. Graph of equation \(6x + 8y – 48 = 0\) meet \(x\) axis at
 
3. The graph of equation \(3x+4y-12=0\) meet \(y\) axis at
 
4. Graphical representation of path of two trains is
