Solution
Consider the amount contributed by two students A and B is Rs X and y. Total amount acontributed by both A and B =Rs100 x+y=100 we can write it as y=100−x Substituting x=25 in the given equation y=100−25=75
y=75
So we get Substituting x=50 in the given equation y=100−50 so we get y=50
x
25
50
y
75
50
Now draw a graph using the points A(25,75) and B(50,50) Join the points AB through a line and extend in both the directions.
