 Hi and welcome to this session. I am Kanika and I am going to help you to solve the following question. The question says, Ramini and Fatima, two students of class 9th of the 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. Let's now start the solution. Let X be the amount contributed by Ramini, Y be the amount contributed by Fatima. In the question it is given that they together have contributed Rs. 100. That means the sum of their contributions is Rs. 100. So according to the question X plus Y is equal to 100. This is the required linear equation. Now we have to draw the graph of this equation. For drawing the graph we need at least two solutions of this equation. Now when X is equal to 0 then the given equation reduces to 0 plus Y is equal to 100 and this implies Y is equal to 100. When Y is equal to 0 then the given equation reduces to X plus 0 is equal to 100 and this implies X is equal to 100. Now we will represent these solutions in the tabular form. So let's make a table. When X is equal to 0 then Y is equal to 100 and when Y is equal to 0 then X is equal to 100. Now we will plot these points on the graph. We have drawn the two axes X and Y. These two axes are perpendicular to each other. The point of intersection of these two axes is the origin. At the origin both the X coordinate and Y coordinate are 0. X coordinate is also known as abscissa and Y coordinate is also known as ordinate. And we are using the scale 1 centimeter is equal to 10 units. These are the two solutions which we have found out. Now the first solution is 0, 100. This means when abscissa is 0 then ordinate is 100. This means this is the required point 0, 100. Now the second point is 100, 0. This means when ordinate is 0 then abscissa is 100. This means this is the required point 100, 0. Now we will join these two points by a straight line. This is the line representing the equation X plus Y is equal to 100. So this completes the solution. Bye and take care.
