Lesson 5.7 Predicting with Linear Models

Solution

1.Not reasonable to be represented by a linear model. 2. Reasonable to be represented by a linear model.

Solution Use the scatter plot from Example 1 to write a linear model for the data

Solution

From Example 2:

is one year from from 1990, so x = 1. Substitute 1 for x is the equation y = 75x y = 75(1) + 50 y = 125 Solution From Exercise 3:
