See answer below

Given: $y = x - 2$

The $x$ is the independent variable. This means we can select any $x$ value and calculate the corresponding $y$ value.

$ul(" "x " "|" "y" ")$
$" " -2" "| -2-2 = -4$
$" "0 " "|" " 0 - 2 = -2$
$" "3" "|" "3-2 = 1$
$" " 6" "| " "6-2 = 4$

graph{x-2 [-10, 10, -5, 5]}
