1. Slant ( oblique) Asymptote

2. A slant asymptote for a function is a slant straight line ( that’s either straight line through the origin or a straight line intersecting the axes at distinct points) which the function follows getting arbitrary closer to as x increases with no bound and as x decreases with no bound. Thus a rational function cannot have both slant and horizontal asymptote(If it has one, then it cannot have the other)

3. We already know that a rational function f(x) = p(x) / q(x), where p(x) and q(x) are polynomials with no common factors, has vertical asymptotes for all x satisfying q(x)=0, and a horizontal asymptote only if the degree of p(x) is either equal or less than the degree of q(x). If the degree of p(x) = 1 + the degree of q(x), then f will have a slant asymptote.
