CPM Homework Help : INT1 Problem 4-9

Copy and complete the table below. Then write an equation for the function.

input $(x)$	$2$	$10$	$6$	$7$	$−3$	$0$	$−10$	$100$	$x$
output $(f(x))$	$−7$				$18$	$3$

Step 1:

We have the starting value, so substitute it into the rule. $y = mx + 3$

Step 2:

Now substitute a known coordinate pair into the equation to solve for $m$ (the growth rate).
