Rajiya and Preethi two students of Class IX together collected Rs.1000 for the Prime Minister Relief Fund for victims of natural calamities. Write a linear equation and draw a graph to depict the statement.

Answer»

Hi,

Solution:

As in the question how much Rajiya alone contribute and Preethi alone contribute not given.

So,let us assume that Rajiya's contribution is x rupees,
and so Preethi contribution is y rupees.

A.T.Q.
Total contribution by both of them is INR 1000/-

so, equation would be
x + y = 1000
How to make graph:

To make graph write the equation in the FORM of ONE's contribution

x = 1000 - y
Now,1) put y = 500
x = 1000-500 = 500

2) put y = 200

x = 1000-200 = 800

3) put y= 700

x = 1000-700 = 300

Take these points and draw the graph.

Hope this helps you
