Answer:
Total distance covered = x km. (Given)
Fair for 1st kilometre = Rs.8 (Given)
Fair for rest distance = (x 1) 5 (Since, it is given that except for first kilometre, the fare for subsequent distance is Rs 5 per km)
Total fair = 8 + (x 1) 5
y = 8 + 5x 5 (Total fare is given to be y)
y = 5x + 3
5x y + 3 = 0
This is the required linear equation
