Question

The total monthly expenditure of a household consist of a fixed expenditure on house rent as Rs.500 and the expenditure on rice which is available at Rs.50 per KG write a linear equation assuming the consumption of rice to be XKG per month and the total expenditure of the household per month was Rs.y draw the graph of the equation

Answer 1

Answer:

Let the total expenditure by Rs y

And the amount of rice be x kg.

According to the given condition,

50x + 500 = y

50x - y + 500 = 0

If x = 1, y = 550

If x = 2, y = 600

If x = 3, y = 650.

Draw the graph accordingly with these values of x and y with

SCALE

x axis 1 cm = 1 unit

y axis 1 cm = 100 units or 50 units (as comfortable)
