Graphing a linear inequality when it is in slope intercept form

The video tutorial explains how to graph the inequality Y < 3X + 3 by treating it as a linear equation in slope-intercept form. It covers identifying the slope and Y-intercept, plotting the graph, determining if the boundary line is dashed or solid, and testing points to decide where to shade the graph. The tutorial emphasizes understanding the slope as a ratio and the Y-intercept as a point, and it demonstrates the process of graphing step-by-step.

What does it mean if the boundary line is dashed in the graph of an inequality?

How can you test if a point is a solution to the inequality Y < 3X + 3?
