Understanding Inequalities and Graphing

The video tutorial explains how to graph the inequality y < -x + 2. It covers determining whether the line is dashed or solid, graphing using slope-intercept form, and deciding where to shade on the graph. The tutorial uses examples to illustrate these concepts, emphasizing the importance of understanding the inequality symbols and their impact on graphing.

What is the equation discussed in the lesson?

• y > x + 2

• y < -x + 2
