4. Solve Linear Systems by Graphing Sections 7.1

5. The Concept • Up until this point we’ve dealt with only one dimensional or two dimensional equations and inequalities • Today we’re going to talk about systems of linear equations • In this kinds of equations, we’re going to find exactly one solution to two sets of criteria or equations • There are several different ways for us to do solve systems of equations • The skills that we learn in this chapter will become invaluable in later chapters

6. Solving by Graphing • The most basic way in which to solve systems of equations is to solve by graphing • Let’s start by graphing y=3x+6 y=2x+4
