Answer 1

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

Given that,

~ Harshit and Harshita, two students in Class IX of a school, contributed ₹ 140 to the Prime

The contributions of Harshit and Harshita as ₹ x and ₹ y.

~ According to statement,

~ Total contribution = ₹ 140

$\red{\rm :\longmapsto\:x + y = 140}$

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

$\rm :\longmapsto\:0 + y = 140$

$\rm :\longmapsto\: y = 140$

Substituting 'y = 0' in the given equation, we get

$\rm :\longmapsto\:x + 0 = 140$

$\rm :\longmapsto\:x= 140$

Substituting 'x = 70' in the given equation, we get

$\rm :\longmapsto\:70 + y = 140$

$\rm :\longmapsto\:y = 140 - 70$

$\rm :\longmapsto\:y = 70$

Hᴇɴᴄᴇ,

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

$\begin{gathered}\boxed{\begin{array}{c|c} \bf x & \bf y \\ \frac{\qquad \qquad}{} & \frac{\qquad \qquad}{} \\ \sf 0 & \sf 140 \\ \\ \sf 70 & \sf 70 \\ \\ \sf 140 & \sf 0 \end{array}} \\ \end{gathered}$

➢ Now draw a graph using the points
