Hi,

I just graphed |x| + y = 2 and I got a straight line!  I entered it as
y= -|x|+ 2 because you have to solve the equation for y before
entering it.  Then, I entered the exact same equation on my TI-84 Plus
Silver, and it came up with the correct graph.  What gives?  Is the TI
the smarter of the two calculators, or am I doing something wrong?

Some of the points should be (-3,-1), (-2,0), (-1,1), (0,2), (1,1),
(2,0), and (3,-1).

Go to MODE -> CAS and check if there is a tick on Rigorous

Thanks!  That change allowed me to produce the correct graph.
