20/20: Consensus Definition of Counseling. The delegates met at the ACA Conference in Pittsburgh in March 2010 and agreed on a unified definition of counseling. Counseling is a professional relationship that empowers diverse individuals, families, and groups to accomplish mental health, wellness, education, and career goals. The delegates made it clear that the definition was a basic framework and that each participating organization is welcome to add a statement that fleshes out the particular specialty or area of focus.
Linear equation. Graph sample of linear equations. A linear equation is an algebraic equation in which each term is either a constant or the product of a constant and (the first power of) a single variable (however, different variables may occur in different terms).
A system of equations is a set of equations that are solved collectively (together). The basic linear system is composed of two linear equations with two variables. Remember that linear equations are equations that represent straight lines when graphed. The term simultaneous equations is also used for systems of equations.
