Writing Equations for Proportional Relationship Between Distance and Time

This video tutorial explains how to represent proportional relationships between total cost and number of items by finding the unit price. It covers calculating unit price, writing proportional equations, and visualizing data through graphs. The tutorial uses examples like pizza slices to illustrate these concepts, emphasizing the constant proportionality and the equation form y = mx.

How can the data be graphed based on the unit cost?

Explain the relationship between the total cost and the number of items.
