Examine the graph below.

A 4 quadrant coordinate plane with the following points: (negative 1, comma negative 3), (0, comma negative 1), (1, comma 1), (2, comma 3), and (3, comma 5).

Use the graph to complete the table:

IN $\left(x\right)$

in (x) column 1 blank

in (x) column 2 blank

in (x) column 3 blank

in (x) column 4 blank

in (x) column 5 blank

OUT $\left(y\right)$

out (y) column 1 blank

out (y) column 2 blank

out (y) column 2 blank

out (y) column 3 $\color{blue}{1}$

out (y) column 4 blank

out (y) column 5 $\color{blue}{5}$

Use the graph to find the rule:
$y=$ ___________
Hint (b):
The graph is a line, so use what you know about rules in tables.
