Question

Draw the graphs for the following table of values, with suitable scales on the axes.
Cost of apples
Number of apples $1$ $2$ $3$ $4$ $5$
Cost (in Rs) $5$ $10$ $15$ $20$ $25$

Solution

Drawing the graph of cost of apples vs number of apples:
Consider number of apples on $x$ -axis and cost on $y$ -axis.
Here, scale: on x-axis: $1 c m = 1 u n i t$
on y-axis: $1 c m = 5 u n i t$
Hence, the graph is plotted as shown below:
