Examine the graph at right.

1. Use the graph to complete the table:

   IN $\left(x\right)$
   OUT $\left(y\right)$

   More Help (a):

   IN ($x$)	blank	blank	$\color{blue}{1}$	blank	$\color{blue}{3}$
   OUT ($y$)	blank	blank	$\color{blue}{1}$	blank	$\color{blue}{5}$

   Hint (a):

   The missing point between the 3rd and 5th points is halfway between the two points.

2. Use the graph to find the rule:
   $y=$ ___________

   Hint (b):

   The graph is a line, so use what you know about rules in tables.
