What is the equation of the oblique asymptote of the graph of $\frac{2x^2+x-13}{2x-5}$?

Enter your answer in the form $y = mx + b.$
Polynomial long division gives us
\[
\begin{array}{c|ccc}
\multicolumn{2}{r}{x} & +3 \\
\cline{2-4}
2x-5 & 2x^2&+x&-13 \\
\multicolumn{2}{r}{2x^2} & -5x &   \\
\cline{2-3}
\multicolumn{2}{r}{0} & 6x &  -13 \\
\multicolumn{2}{r}{} & 6x & -15 \\
\cline{3-4}
\multicolumn{2}{r}{} & 0 &+  2 \\
\end{array}
\]Hence, we can write
$$\frac{2x^2+x-13}{2x-5} = x + 3 + \frac{2}{2x-5}.$$So we can see that as $x$ becomes far from $0$, the graph of the function gets closer and closer to the line $\boxed{y = x+3}.$
