CLASS - 9
EXERCISE - 4.3
Q7) 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.
Solution:
Let Yamini’s donation be ₹x and Fatima’s donation be ₹y
According to the question;
x+y = 100
We know that,
when x = 0 , y = 100
when x = 50, y = 50
when x = 100, y = 0
The points to be plotted are (0,100), (50,50), (100,0)
