Graphing Linear Functions in Algebra 1

This video tutorial focuses on graphing linear functions, specifically using slope-intercept and point-slope forms. It begins with an introduction to the different forms of linear equations and their applications in graphing. The tutorial then provides a step-by-step guide on how to graph equations in slope-intercept form, identifying the slope and y-intercept, and plotting points on a graph. It also covers graphing in point-slope form, addressing the challenges of negative values and demonstrating how to plot points and draw lines accurately. The video emphasizes practice and provides tips for accurate graphing.
