Write About the Math
A food truck tracks how many tacos it sells and how much salsa it uses. After recording data for a week, the owner plots the points on a graph and notices they form a straight line. This helps the owner predict exactly how much salsa to prepare for any number of tacos?
Say your answer to a partner first. Then write it, using at least two of these words:
Model: The points form a straight line, and each sundae adds 2 ounces of sauce. — Listen for 'straight line through the origin' and the connection that the constant 2-ounce step shows a proportional relationship.
