of linear equations, systems of linear equations, and linear functions. The ability to analyze and create linear equations, inequalities, and functions is essential for success in college and career, as is the ability to solve linear equations and systems fluently. Heart of Algebra questions vary significantly in form and appearance. Linear Systems. The possible graphs of a. linear system in two unknowns are as follows. 1. The graphs intersect at exactly one point, which gives the (single) ordered pair solution of the system. The system is consistent and the equations are independent.Consequences of Geometric Interpretation It follows that a given system of equations ax + by = c dx + ey = f has either 1 A unique solution (when the two lines intersect in a point) or ….
