What is a Slant Asymptote?

A slant asymptote, also known as an oblique asymptote, occurs in rational functions when the degree of the numerator is exactly one greater than the degree of the denominator. It's a straight line that the graph of the function approaches as x tends to +∞ or -∞. To find it, you perform polynomial long division or synthetic division of the numerator by the denominator. The quotient (ignoring the remainder) gives the equation of the slant asymptote in the form y = mx + b. This tool helps you quickly calculate and visualize this asymptote, making it easier to understand the behavior of rational functions.
