Yeah they are =P. Remember, if ymax = 5, ymin = -5, xmax = 5, xmax = -5 -
you will NOT be getting the right graph =P. There is a greater width than
height. Try looking at it in something like ymin = -3, ymax = 3, xmin =
-5, xmax = 5.

The negative reciprocal is not a linear equation, it is a hyperbola.
