Here are recipes for two different banana cakes. Information for the first recipe is shown in the table. sugar (cups)flour (cups)row 1row 2row 3The relationship between cups of flour y and cups of sugar xin the second recipe is y=74x

If you used 4 cups of sugar, how much flour does each recipe need?

What is the constant of proportionality for each situation and what does it mean?

Problem 2 (from Unit 2, Lesson 6)Show that the two figures are similar by identifying a sequence of translations, rotations, reflections, and dilations that takes the larger figure to the smaller one. Problem 3Create a graph that shows three linear relationships with different y-intercepts using the following slopes, and write an equation for each line.Slopes:

15

35

65

Problem 4The graph shows the height in inches, h, of a bamboo plant t months after it has been planted.

Write an equation that describes the relationship between h and t.

After how many months will the bamboo plant be 66 inches tall? Explain or show your reasoning.
