Answer 1

Appropriate Question :-

The weight (y) in kg and age (x) in years of a person expressed by the equation y = 2x. Draw the Age - Weight graph.

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

Given equation is

$\rm \: y = 2x$

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

$\rm \: y = 2 \times0$

$\rm\implies \:y = 0$

Substituting 'x = 1' in the given equation, we get

$\rm \: y = 2 \times 1$

$\rm\implies \:y = 2$

Substituting 'x = 2' in the given equation, we get

$\rm \: y = 2 \times 2$

$\rm\implies \:y = 4$

Hᴇɴᴄᴇ,

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

$\begin{gathered}\boxed{\begin{array}{c|c} \bf x & \bf y \\ \frac{\qquad \qquad}{} & \frac{\qquad \qquad}{} \\ \sf 0 & \sf 0 \\ \\ \sf 1 & \sf 2 \\ \\ \sf 2 & \sf 4 \end{array}} \\ \end{gathered}$

➢ Now draw a graph using the points (0 , 0), (1 , 2) & (2 , 4)
