Chapter 3.3, Problem 4SBE

Making a Linear Model The data in Exercise S-2 are not linear, but if we omit the first point, the remaining data are linear. Make a linear model for these last three points.

S-2. Testing Data for Linearity Test the following data to see whether they are linear.

$\mathit{x}$	$2$	$4$	$6$	$8$
$\mathit{y}$	$12$	$17$	$21$	$25$
