Explanation

The equation y = 20x + 150 is in the form y = ax + b, representing the linear relationship between the bill amount (y) and the internet data used (x). The coefficient 'a' (20) is the variable cost per GB, and the constant 'b' (150) is the fixed cost.

Solution Steps

  1. Step 1: Identify the form of the equation as y = ax + b, where y is the bill amount in Rupees and x is the number of GB of the internet data used.

  2. Step 2: Recognize that the coefficient 'a' (20) represents the cost per GB of data used.

  3. Step 3: Recognize that the constant 'b' (150) represents the fixed monthly cost.
