Your graph should look something like this. This graph contains a linear solution that has y values that equal the x value. If you look, when x=1, y=1 also. When x=2, y=2 also, and the pattern continues forever.
x | Process | y
1 x=y 1
2 x=y 2
3 x=y 3
4 x=y 4
.... ..... ....
I hope this helped!! Have an amazing day :D
