Yamini and Fatima, two students of Class IX of a school, together contributed ₹ 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 ₹ x and ₹ y.) Draw the graph of the same.
Let the contribution of Yamini be x and that of Fatima be y. According to problem, x+y=100 ...(1) Now , putting the value x=0 in (1) 0+y=100 y=100 So, the solution is (0,100) Putting the value x=50 in (1) 50+y=100 y=100–50 y=50 So, the solution is (50,50) Putting the value x=100 in (1) 100+y=100 y=100–100 y=0 So, the solution is (100,0)
