Graphing in Slope Intercept Form: y = mx + b

The video tutorial, hosted by Catherine, teaches graphing using the slope-intercept form y = mx + b. It covers identifying the slope and y-intercept, plotting points, and drawing lines. Examples include graphing equations like y = 2x - 4 and y = -3x + 5. The tutorial also explains solving equations for y and provides a self-quiz for practice.
