Exploring Non-Proportional Tables

The video tutorial covers non-proportional relationships, focusing on how to derive equations from tables and graph them. It explains the equation y = mx + b, detailing the roles of slope (m) and y-intercept (b). The tutorial provides step-by-step guidance on finding these components from a table and graphing the resulting equation. It concludes with a practice problem and encourages students to seek help if needed.

What is the main focus of today's lesson?

• Understanding proportional relationships

• Exploring exponential functions

• Learning about non-proportional relationships

• Studying quadratic equations
