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 the given data will satisfy and also plot its graph.
The correct option is A: x+y=100
Let the contribution of Yamini be Rs. x and that of Fatima be Rs. y.
Then, x+y=100 is the required linear equation.
Now, to draw its graph let us find out its co-ordinate on XY-plane.
