Graphing a linear inequality on a coordinate axis

The video tutorial explains how to graph the equation y = 5x - 8, starting with writing it in slope-intercept form. It covers identifying the slope and y-intercept, graphing the equation, and understanding the differences between dashed and solid lines for inequalities. The tutorial also demonstrates how to determine shading using test points, emphasizing the importance of solving the equation for y to predict shading direction.

What does it mean when a line is dashed in the context of graphing inequalities?
