Primary Subjects: Algebra, Discrete

Related Topics: coordinate plane, function properties, functions, graph, linear functions, lines, pre-calculus, vertical line test

Learn about the vertical line test for functions by trying to connect points in the plane to build a function. When you have connected all of the points, you will be told if your graph is a valid graph of a function. Vertical Line Test is one of the Interactivate assessment explorers.
