The horizontal asymptote of a rational function can be found by comparing the degrees of the numerator and denominator. If the degrees are the same, the horizontal asymptote is the ratio of the leading coefficients. Here, both the numerator and denominator are of degree 2, with leading coefficients of 7. Thus, the horizontal asymptote is $y = \frac{7}{7} = 1$.
