This activity is available below or in a printable document.

1. Use the scatterplot to predict the value of y when x = 7. ________________

2. The number of visitors to the homepage of an online magazine can be modeled by the equation y = 1100.74x − 1976.47, where x = 5 represents the year 2005 and y represents the total number of visitors.

Use the linear model to predict the number of visitors in the year 2034.

3. For consecutive weeks, the manager of a local restaurant collected data on the number of cheese pizzas sold each week. The data is shown in the scatterplot below.

Can the given line be used to make reasonable predictions of the number of cheese pizzas that will be sold in upcoming weeks? Explain your reasoning.
