उत्तर
Here, over is an independent variable and run is a dependent variable. So, we take overs on x-axis and runs on y-axis.
Let us choose the following scale:
On x-axis: 1 cm = 1 over
On y-axis: 1 cm = 1 run
Now, let us plot (I,2), (II,1), (III,8),...,(X,2) for team A and (I,5), (II,6), (III,8),....(X,10) for team B. These points are joined to get the graph representing the given information as shown in the figure below.
