1.3 The Intersection Point of Lines System of Equation A system of two equations in two variables looks like: – Notice, these are both lines. Linear Systems Graphically Two lines can: – Intersect – Be parallel – Be the same line Which means the number of solutions (or intersection points) is, respectively: – One – None – Infinite

2
1.3 The Intersection Point of Lines Solving Systems of Equations In order to solve a system, you: – Find the point of intersection Graphically Algebraically There are some other more complex ways we will discuss later – Or state the number of solutions When there are infinite or no points of intersection Find the point of intersection. (Solve the system)
