Question 4626: how would you graph |x+1|=y? what does the | | mean?

You can put this solution on YOUR website!
Those marks indicate it is an "absolute value", and an absolute value graph is "V" shaped
Absolute value is a positive number always. (The distance from zero to the number)
Example:
}3|=3
|-3|=3
To plot any graph, you can always pick x coordinates and create a table of points to plot.
In your question,
|x+1|=y,
We can pick the values of
-2,-1 and 1 to solve for y:
|-2+1|=1
|-1+1|=0
|1+1|=2
Plot three points:
(-2,1)
(-1,0)
(1,2)
and extend your lines.
