This video tutorial by eMath Instruction covers Unit 4, Lesson 2 on graphing linear functions. It begins with a review of the basics of linear functions, including equations, slope, and y-intercept. The lesson progresses through exercises that involve matching equations to lines, graphing lines from equations, and rewriting equations to identify slope and y-intercept. The tutorial emphasizes understanding the impact of slope and y-intercept on a line's graph and concludes with a summary of the key concepts and skills learned.
