Warm-up Determine what the relationship is when comparing cups of sugar to the cups of flour. Is the relationship between x and y proportional or non-proportional? How do you know?

Do the graphs show proportionality?

Pages 20-21 Jada’s Steps Noah’s Steps Based on the points you have in your table, how would you scale and label the graph to the right?

Page 26 y = x What is being compared in the graph (x and y values)? Find three values that exist on the line in the graph. Create a table as shown to demonstrate these values. Write an equation that shows the relationship using x to represent the grams of fish and y to represent the number of calories. y = x
