A taxi charges Rs.8 for the first km and Rs.5 per km for subsequent distance covered. Taking the distance covered as x km and total fare Rs.y, write a linear equation depicting the relation in x and y. Draw the graph between x and y and find taxi charges for covering 4 km.

Expert Answer
Let x axis represent the distance in kilometer and y axis represent the fare in rupees
As per the given information, the required linear equation will be,
y = 8 + 5(x – 1)
∴ y = 8 + 5x – 5
∴ y = 5x + 3
This equation can be represented by a graph.
x |
0 |
1 |
2 |
y = 5x + 3 |
3 |
8 |
13 |
As can be observed from the graph, the taxi charges for covering 4 km. is at the point D(4, 22) hence, it is Rs.22
