5.1 Linear Equations and Graphs of Linear Functions
Linear Equations • Solutions of Linear Equations • Linear Functions • Slope • Slope-Intercept Form • Sketching Lines by Intercepts • Linear Regression
In this chapter, we will discuss various techniques for solving systems of equations, which are groups of equations that contain more than one unknown. The methods we study assume that the equations are of a specific type, called linear equations. In this first section, we will define a linear equation and describe ways of graphing linear equations in two variables.
LINEAR EQUATIONS
An equation is called linear in a given set of variables if each term contains only one variable, to the first power, or is a constant. This is illustrated in ...
