Question

A public bus in a city is as follows for the first two kilometers the fare is ₹12 for the subsequent distance it is ₹10 per km .Taking the distance covered as xkm and total fare as ₹y. Write a linear equation for this information and draw its graph.​

Answer 1

Given :  for the first two kilometers the total fare is Rs. 12 and the subsequent distance is Rs. 10 per km

To find :   a linear equation taking x as distance covered and y as fare.

Solution:

Distance Covered  = x

Fare = y

for the first two kilometers the total fare is Rs. 12  

the subsequent distance is Rs.10

y  = 12  + 10(x - 2)     x   ≥  2  

= y = 12 + 10x  - 20

= y   =  10x  - 8 where  x   ≥  2  

y   =  10x  - 8 where  x   ≥  2
