How to graph absolute value on TI-84 Plus Calculator?

Question

I'm trying to graph these equations:

1) IyI = Ix-3I

2) y = IxI - x

I know that you go to y=, then math button, number button, and abs(

but in the first equation, I don't know how to put the y into absolute value notation. And, in the second equation, how do you only put the first x into absolute value notation?

Thank you so much for the help!!!!!!!

Answer 1

Not sure about the first one, but for the second one it is y=abs(x) - x
