If $y = x$, the values of $y$ are identical to the values of $x$. A table representing this linear relationship would show that for every $x$, the corresponding $y$ value is the same.

Here's what the table might look like:

$x$	$y$
-3	-3
-2	-2
-1	-1
0	0
1	1
2	2
3	3

This table shows a direct one-to-one relationship, where $y$ equals $x$ for all points. You can extend this table to any values of $x$ as needed.

Would you like to explore details on how this linear function behaves graphically or algebraically? Here are some questions for further exploration:

1. What is the slope of the line represented by $y = x$?
2. How would the table change if the function were $y = 2x$?
3. How does the graph of $y = x$ compare to other linear equations?
4. What happens if you change the equation to $y = x + 3$?
5. Can this relationship be represented in terms of a real-world example?

Tip: The equation $y = x$ represents a line with a slope of 1 passing through the origin (0,0).
