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
and Rs
). Draw the graph of the same.
Solution:
Let contribution made by Yamini = Rs
Let contribution made by Fatima = Rs
According to given condition, we have
To draw graph of
, we will find 3 or 4 set of solutions.
Putting
in the equation
, we get
Therefore,
is one of the infinite possible solutions.
Similarly, putting
in the equation
, we get
Therefore,
is one of the infinite possible solutions.
Putting
in the equation
, we get
Therefore,
is one of the infinite possible solutions.
Therefore, three different solutions for equation
are:
Now, we plot all these three points on the Cartesian plane. When we join these points, it makes a straight line.
