Answer 1

Answer:

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 asx and y.) Draw the graph of the same.y

Answer 2

x 0 50 100

y 100 50 0

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)
