Question

The following table shows the sales of a commodity during the years $2000$ to $2006$.
$\begin{array}{cccccccc}\text{Years}& 2000& 2001& 2002& 2003& 2004& 2005& 2006\\ & & & & & & & \\ \text{Sales (in lakhs of Rs)}& 1.5& 1.8& 2.4& 3.2& 5.4& 7.8& 8.6\end{array}$
Draw a graph of this information.

Answer 1

Here, year is an independent variable and sales is a dependent variable. So, we take year on the x-axis and sales on the y-axis.
Let us choose the following scale:
On x-axis: $2cm=1$ year
On y-axis: $2cm=1$ lakh rupees
Assume that on x-axis, origin (O) represents $1991$.
So, the coordinates of $O$ are $(1991,0)$.
Now, let us plot $(2000,1.5),(2001,1.8),(2002,2.4),(2003,3.2),(2004,5.4),(2005,7.8)$ and $(2006,8.6)$. These points are joined to get the graph representing the given information as shown in the figure below.​
