Graphing Lines: Slope and Solution Points

Mrs. Angel teaches students how to graph linear functions using the slope and a solution point. The lesson covers the concepts of slope (m) and intercept (b) in the equation y = mx + b. Students learn to graph lines by starting at a solution point and using the slope to find additional points. The video includes examples of graphing different linear functions and emphasizes the importance of checking solutions. The lesson concludes with encouragement for students to practice on their own.
