Let 1 over=length of 1 side of the smallest squares along x-axis i.e., x-axis represents the number of over.

And 1 run= length of 5 side of the smallest square along y-axis i.e., y-axis represent the scores at the end of the over.

The points of the graph can be represented as shown above. They lie on a line.

A graph in which we obtain a line on joining all the points is called a liner graph. Hence the graph obtained from the data given is a liner graph.
