5.7Predicting with Linear Models

Solution

Solution1. Not reasonable to be represented by a linear model.

2. Reasonable to be represented by a linear model.

Solution

Use the scatter plot fromExample 1 to write a linearmodel for the data

Solution

Solution

From Example 2:

4. 1991 is one year from from 1990, so x = 1.

Substitute 1 for x is the equation y = 75x + 50.

y = 75(1) + 50

y = 125

Solution

From Exercise 3:
