Answer:

strong negative linear correlation

Explanation:

Correlation coefficient is used in statistics to describe a relationship between two variables. A negative correlation describes the extent to which two variables move in opposite directions i.e. an increase in a variable is associated with a decrease in the other variable.  

Correlation coefficient is between -1 and 1.

-1 shows a perfect, linear negative correlation, and 1 shows a perfect, linear positive correlation.

In this example, -90 shows a strong negative correlation.
