The form of an association can be linear or non-linear.
form
A line of best fit shows a trend in the data representing where the data falls.
line of best fit
If one variable decreases as the other variable increases.
negative association
A line that slopes upward from left to right on a graph.
positive slope
A ratio that describes how steep (or flat) a line is.
slope
An equation where the constant m is the slope, and b is the y-intercept of the graph.

strength of an association
