CPM Homework Help : GB8I Problem 2-102

Write the equation for the line containing the points listed in the table below.

$x$	$–1$	$1$	$3$	$5$
$y$	$2$	$16$	$30$	$44$

Hint:

Find the rate of growth per unit. This is the slope.
Do this by finding the pattern in the graph, or by plotting two of the points and making a slope triangle.

More Help:

If $−1$ is $2$ and $1$ is $16$ , what is $0$ ?
This is the $y$ -intercept. Use it along with the slope to write a $y = mx + b$ equation.
