If the system of equations x+5 y+6 z=4, 2 x+3 y+4 z=7, x+6 y+ a z= b has infinitely many solutions, then the point (a, b) lies on the line
If the system of equations
$$\begin{aligned}
& x+5 y+6 z=4, \\
& 2 x+3 y+4 z=7, \\
& x+6 y+\mathrm{a} z=\mathrm{b}
\end{aligned}
$$
has infinitely many solutions, then the point (a, b) lies on the line
