The straight lines \( l_1 \) and \( l_2 \) pass through the origin and trisect the line segment of the line \( L: 9x + 5y = 45 \) between the axes. If \( m_1 \) and \( m_2 \) are the slopes of the lines \( l_1 \) and \( l_2 \), then the point of intersection of the line \( y = (m_1 + m_2)x \) with \( L \) lies on:
