A taxi charges .Rs 20 for the first kilometre and @12 .Rs per km for subsequent distance covered. Taking the total distance covered as x km and total fare .Rs y, write a linear equation depicting the relation between x and y. Draw the graph between x and y.
Form your graph, find the taxi charges for covering
(a) 12 km and (b) 20 km.

Explanation

To solve the problem step by step, we will first derive the linear equation that represents the relationship between the total distance covered (x km) and the total fare (y Rs) for the taxi charges.

### Step 1: Understand the Taxi Fare Structure
- The taxi charges Rs. 20 for the first kilometer.
- For each subsequent kilometer, it charges Rs. 12 per kilometer.

### Step 2: Formulate the Equation
1. For the first kilometer, the fare is Rs. 20.
