Answer:
Let the contributions of Yamini and fatima be Rs x and y respectively. Then their total contributions is Rs (x+y) . But, the total contribution is Rs 100 (given)..
This is the required equation satisfying the given data :
Putting x = 0 in (i), we get y = 100.
Thus, we obtain the following table exhibiting the coordinates of two points on line (i).
Now, plot these points A (0,100) and B (100,0) on the graph paper on a suitable scale (1cm = 20, say) and draw the line passing through A and B. The line so obtained is the graph of the line x + y = 100 ..
