Let $\displaystyle A(a, b), B(3,4)$ and $\displaystyle C(-6,-8)$ respectively denote the centroid, circumcentre and orthocentre of a triangle. Then, the distance of the point $\displaystyle P(2 a+3,7 b+5)$ from the line $\displaystyle 2 x+3 y-4=0$ measured parallel to the line $\displaystyle x-2 y-1=0$ is
