Question

Ravi and Raju collected 1000 rs for prime minister’s relief fund. Draw the graph to represent this situation.​

Answer 1

$\large\underline{\sf{Solution-}}$

Given that,

• Ravi and Raju collected Rs 1000 for Prime Minister’s relief fund.

Let assume that

• Ravi contribution is Rs x

• Raju contribution is Rs y

So, According to statement

$\rm :\longmapsto\:\boxed{\tt{ \: \: x \: + \: y \: = \: 1000 \: \: }}$

➢ Substituting 'x = 0' in the given equation, we get

$\rm :\longmapsto\:0 + y = 1000$

$\rm :\longmapsto\: y = 1000$

➢ Substituting 'x = 500' in the given equation, we get

$\rm :\longmapsto\:500 + y = 1000$

$\rm :\longmapsto\:y = 1000 - 500$

$\rm :\longmapsto\:y = 500$

➢ Substituting 'x = 1000' in the given equation, we get

$\rm :\longmapsto\:1000 + y = 1000$

$\rm :\longmapsto\:y = 1000 - 1000$

$\rm :\longmapsto\:y = 0$

Hᴇɴᴄᴇ,

➢ Pair of points of the given equation are shown in the below table.

$\begin{gathered}\boxed{\begin{array}{c|c} \bf x & \bf y \\ \frac{\qquad \qquad}{} & \frac{\qquad \qquad}{} \\ \sf 0 & \sf 1000 \\ \\ \sf 500 & \sf 500 \\ \\ \sf 1000 & \sf 0 \end{array}} \\ \end{gathered}$

➢ Now draw a graph using the points.
