**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.

Let the contribution amount by Yamini be x and contribution amount by Fatima be y, then, we have, x + y = 100
Taking the scale, 1 unit = Rs 10 |
