An outlier is a data point that lies far outside the general cluster of other data points. Looking at all four plots, the first plot has a point on the x-axis (near x=30, y=0) that is completely separated from the main group of points which have y-values ranging from ~40 to 100 and x-values from ~20 to ~90.
