Module 8: Graphing Linear Equations

math students studying togetherThe graph of a linear equation represents the set of all points that satisfies the equation. Linear equations can be graphed using several different methods. Depending on the form that a linear equation is presented in, you may choose to graph it by using its slope and y-intercept, by using its x-intercept and y-intercept, or by interpreting the equation as a transformation of the linear parent function, y = x. In this module, you will explore these methods of graphing linear equations.
