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.
Answer :
Let the contributions of Yamini and Fatima together towards the Prime Minster’s Relief Fund to help the earthquake victms are Rs. x and Rs. y, respectively.
Then, by given condition, x + y = 100 … (i)
| x | 0 | 100 |
|---|---|---|
| y = 100 - x | 100 | 0 |
| (x, y) | B (0, 100) | A (100, 0) |
Here, we plot the points B (0, 100) and A (100, 0) on graph paper and join all these points to form a line AB.
