Question

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 1

Solution :-

Let yamini's contribution be

$₹x$

Let fatima's contribution be

$₹y$

Total contribution = ₹100

$⇒ x + y = 100$

$y = 100 - x \: \: \: \: \: \:$

⇒ If we will take x as 50 then y will be

➵ y = 100 - x

➵ y = 100 - 50

➵ y= 50

⇒ If we will take x as 60 then y will be

➵ y = 100 - x

➵ y= 100 - 60

➵ y= 40

⇒ If we will take x as 70 then y will be

➵ y = 100 - x

➵ y= 100 - 70

➵ y= 30

So

x , 50 , 60 , 70

y , 50 , 40 , 30

Plot

(50,50) (60,40) (70,30)
