This is similar to Problem 2 from you Section 2.6 worksheet.

The $x$ and $y$ values in the following tables represent points on a line. Find the slope of each line.

a)

$\ x \ $	$\ y \ $
$0$	$\ 8 \ $
$9$	$0$
$18$	$\ -8 \ $
$27$	$\ -16 \ $

Slope:

b)

$\ x \ $	$\ y \ $
$0$	$\ 14 \ $
$3$	$0$
$-3$	$\ 28 \ $
$-6$	$\ 42 \ $

Slope:

c)

$\ x \ $	$\ y \ $
$6$	$\ -2 \ $
$-6$	$-50$
$18$	$\ 46\ $
$-12$	$\ -74 \ $

Slope:
