If your graph digits doesn't go that far (i.e. -11 on y axis and till -7 on x axis) then you can try lowering down the scale. Which means, to represent 1 unit you can use 0.5 of the graph rather than 1 Or you can use other scale. Reduce the scale as per your convenience and mention it on the graph.
