The straight lines $\mathrm{l}_1$ and $\mathrm{l}_2$ pass through the origin and trisect the line segment of the line L: 9x + 5y = 45 between the axes. If $\mathrm{M}_1$ and $\mathrm{M}_2$ are the slopes of the lines $\mathrm{l}_1$ and $\mathrm{l}_2$, then the point of intersection of the line y = (m1 + m2) x with L lies on
