Give an equation with a vertical asymptote of 0 and a slant asymptote of -x

The equation of the slant asymptote is put in the standard form
and it is written as:

y = mx + n, where m is the slope of the
asymptote and n is the y intercept.

The equation of the slant
asymptote is:

y = -x

m = -1 and n =
0

The equation y = -x is the equation of the bisectrix of the 2nd or
the 4th quadrant.

So, the slant asymptote y = -x is the bisectrix of
the 2nd or the 4th quadrant.

If the vertical asymptote of a function
is x = 0 that means that the function is discontinuous in the point that has the x coordinate x =
0.

The domain of definition of the function that has the vertical
asymptote x = 0 does not contain the value x = 0.
