Question

two students A and B contributed rupees hundred towards the Prime Minister relief fund to help the earthquake victim write a linear equation to satisfy the above data and draw its graph​

Answer 1

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..
