In Linear Equations and Functions we begin with Functions vs. Relations to define a what a function is and how it is used to establish a mathematical relationship between two variables. Intensify your previous knowledge of Linear Equations and explore how linear relationships can also be functions. With a review of Linear Equations and Functions, challenge yourself with Direct Variation Equations to gain a better understanding of slope, which is an important concept in more advanced math topics, such as Calculus.
