How to graph y = | x - 2 | ?

There are a few things we can see right away:


A value greater than or equal to 0 will always be returned by the absolute value function. And so the value of ${\displaystyle y}$ in our question can't be negative.


when ${\displaystyle x=2,y=0}$


when ${\displaystyle x=1,3;y=1}$


when ${\displaystyle x=0,4;y=2}$


and so on.
The graph ends up looking like this:
graph{abs(x-2) [-7.21, 12.79, -2.12, 7.88]}
