A linear relationship (or linear association) is a statistical term used to describe a straight-line relationship between two variables. Linear relationships can be expressed either in a graphical format or as a mathematical equation of the form y = mx + b. Linear relationships are fairly common in daily life.
A linear relationship is a relationship on a graph that takes the information of two different things and shows that they are growing a constant rate. It is usually expressed as <em>y</em> =<em> mx</em> + <em>b</em>.
