Q.7. Yamini and Fatima, two students of Class IX of a school, together contributed Rs 100 towards the Prime Minister’s Relief Fund to help the earthquake victims. Write a linear equation which satisfies this data. (You may take their contributions as Rs x and Rs y.) Draw the graph of the same.

Solution:

Let the contribution amount by Yamini be x and contribution amount by Fatima be y, then, we have,

x + y = 100

x

0

100

y

100
