App shows multiple representations of relations between a domain and range. Designed for instruction on relations generally, on functions generally on more specifically on linear equations and linear functions. It is designed to be a flexible tool for classroom lectures and for generating screen shots for insertions into paper or digital texts. The default null selection allows you to produce blank images to students to fill out on paper. You adjust the 5 points on the graph. The points can only land on points with integral abscissa and ordinate. The table, list of ordered pairs and bubble diagram adjust dynamically. If the relation is linear, the equation and linear pattern may be selected to appear. Note that in this exercise both the domain and range are discrete. The line is described as a "linear pattern" because it does NOT represent the actual function.
