Answer 2

Answer:

y = 20x + 500

Step-by-step explanation:

Let's consider that the amount of extra milk consumed by the family is x, and the total expenditure on milk is y.

Since, the rate of extra milk consumed by the family is 20 Rs/kg.

So, the expenditure on extra milk is 20x.

Hence, the linear equation can be given by

y = 20 x + 500

The graph can be drawn as shown in figure:

• when x = 0

    => y = 500

• when y = 0

    => x = -25
