Inclined asymptote can be found by calculating the limit of log(4)*(x - 2), divided by x at x->+oo and x ->-oo
$$\lim_{x \to -\infty}\left(\frac{\left(x - 2\right) \log{\left(4 \right)}}{x}\right) = \log{\left(4 \right)}$$
Let's take the limitso,
inclined asymptote equation on the left:
$$y = x \log{\left(4 \right)}$$
$$\lim_{x \to \infty}\left(\frac{\left(x - 2\right) \log{\left(4 \right)}}{x}\right) = \log{\left(4 \right)}$$
