Describe three types of relationships you may observe from a graph (and the shapes of the graphs) and the formula used to model that relationship.

data correlation

positive or direct relationships between variables An increase in the value of x is more likely associated with an increase in the value of y

negative or inverse relationships between variables If the points tend to cluster around a line that runs from the upper left to lower right of the graph, then the relationship between the two variables is negative or inverse

scattered data points If the data points are randomly scattered, then there is no relationship between the two variables; this means there is a low or zero correlation between the variables
