What's Negative Correlation?
If the y-value decreases as the x-value increases then you have a negative correlation. Meaning that the line-of-fit has a negative slope.

How Do You Use a Scatter Plot to Find a Line of Fit?
What is a line-of-fit? Given a data set, plot the ordered pairs on a graph. It looks like a scatter plot. Now estimate, and draw a line that best fits what the data represents. That is your line-of-fit.
