Practice makes perfect
To determine whether the data shows a linear relationship, let's begin by visualizing it. If we treat the table as a set of points, we can graph the given data as a scatter plot. Do you see any trends?
Looking at the graph, it does not appear that there is a recognizable trend. Therefore, we can conclude that the data does not show a linear relationship.
