Step 1
From the scatter plot,
it is observed that there exists a strong negative linear relationship between two variables,
but in between these two variables there is not perfect negative linear relationship
so that correlation do not equal to -1,
but it is equal to -0.93.
The points is from upper left to bottom right with negative slope.
