Here is a table of values for the equation y = |x| - 2:
x | y
-----
-3 | 1
-2 | 0
-1 | -1
0 | -2
1 | -1
2 | 0
3 | 1
To graph the equation, plot the points in the table on a coordinate plane and connect them with a line. The graph will be a "V" shape, with the vertex at the point (0, -2) and the arms of the "V" extending upward. The graph should look like this:
(0, -2)
