Exercise 11 Page 257

One way to graph a function rule is by making a table of values and substituting some arbitrary values for $x .$ Doing so will give the corresponding values of $y,$ which we can use to form $(x, y)$ coordinate pairs.

$x$	$3 x - 2$	$y$	$(x, y)$
$- 1$	$3 (- 1) - 2$	$- 5$	$(- 1, - 5)$
$0$	$3 (0) - 2$	$- 2$	$(0, - 2)$
$1$	$3 (1) - 2$	$1$	$(1, 1)$

Let's plot these points on a coordinate plane.

By connecting all of our points with a line, we form the graph of the function rule.
