1. The amount of fiber and potassium in a cereal can be modeled by y = 27x+38 where y is the potassium content in milligrams and x is the fiber content in grams

- Define the independent and dependent variable

- Identify the slope

- Identify the vertical intercept

- Determine the potassium content when the fiber is at 5 grams

2. Duration of a roller coaster ride in seconds can be modeled as a function of the initial drop height in feet: y=85.83+0.397x where y is the duration of the ride in seconds and x is the initial drop height in feet

- Define the independent and dependent variable

- Identify the slope

- Identify the vertical intercept

- A new roller coaster advertises an initial drop height of 200 feet. How long would you predict the ride lasts?
