Identify the Graph of a Real World Situation | 8.EE.B.5

The video tutorial guides students through identifying the correct graph that represents a real-world situation involving the cost of pens. The teacher explains the problem, analyzes four graphs, and uses the concept of slope and origin to eliminate incorrect graphs. The correct graph is identified by writing an equation and verifying it against the graphs. The lesson concludes with a summary of the key points.
