Exploring Non-Proportional Linear Relationships

The video tutorial explores multiple representations of non-proportional relationships. It begins with a verbal description of a taxi fare scenario, converting it into an equation and table, and then graphing the relationship. The tutorial then examines a kite descending, using a table to derive an equation and verbal description, and graphing the data. Key concepts include identifying the rate of change and y-intercept in y=mx+b form, and translating between verbal, tabular, and graphical representations.

What does 'm' represent in the equation y = mx + b?

• The rate of change

• The total cost

• The initial value

• The number of miles
