This chapter is one of the core branches of Algebra 1. Your journey through lines begins with a super thorough tour of rate of change and slope along with direct variation. From there you will learn the three forms of a linear function: slope-intercept form, point-slope form, and standard form. In your explorations of these three forms, you will learn to graph, construct, and use these linear functions in various scenarios. You will then rock horizontal and vertical lines followed by mastering the ins and outs of parallel and perpendicular lines. The chapter finishes off with a study of scatterplots and the all-important graphing of absolute value functions to understand how graphs are shifted in all directions. Let’s start up this linear awesomeness!!!
