Question

neha and richa two students of class 9th of a school, together contributed rs.100 towards the prime minister's relief fund to help earthquake victims. assume neha's contribution to be x and that of richa to be y .write a linear equation which this data satisfies and draw a graph of the same.

Answer 1

Answer:

x + y = 100

Step-by-step explanation:

Given neha and richa two students of class 9th of a school, together contributed rs.100 towards the prime minister's relief fund to help earthquake victims. assume neha's contribution to be x and that of richa to be y .write a linear equation which this data satisfies and draw a graph of the same.

The amount contributed by Neha is x and the amount contributed by Richa is y.

So together x + y = 100

 Taking x = 0 we get y = 100

 Taking y = 0, we get x = 100

So plotting the graph for the equation x + y = 100 we get (0, 100) and (100, 0)
