Answer 1

The graph is drawn in excel by first selecting the data then insert then recommended charts then scatter diagram, and then we have to set the limits of x and y axis accordingly. Here i have set the limit of y to be maximum 500 and x limit to be maximum 200 as the graph given in the options are having this limit
