Question

the taxi fare in  a city is a s follows :
for the 1st km the fare is Rs.8 and for the subsequent distance it is Rs.5 per km.
taking the distance covered as Rs.x and total fare as Rs.y,
write a linear equation for this information.

Answer 1

Let the total distance covered by the taxi = x km
Fare for the left distance = Rs (x -1) 5

So, the total fare of the taxi = [8 + (x - 1) 5]RS

So the equation will be, 

y = 8 + 5x - 5
=> y = 5x + 3
=> 5x - y + 3 = 0 (ans)

Answer 2

the answer is
5x - y + 3 = 0
