#### Work Step by Step

First, try to draw a best fitting line. If the best fitting line has a positive slope, the correlation is positive. If it has a negative slope, the correlation is negative. If it is impossible to tell what the slope of the line should be, there is no correlation. Doing this, we see that it is a negative correlation. The correlation is about $-1$ as the data come close to forming a straight line.
