In a system of two linear equations with two unknowns, the assignment of the second equation is inadvertently blurred, but we know that the first component of the solution of the system is \(x=-1\). We do not know the value of \(y\), but the part of the figure illustrating the graphical solution is preserved. The first equation is \(x-y+2=0\). Determine the second (blurred) equation of this system.
\(7x-11y+18=0\)
\(x-y+2=0\)
\(7x+11y-18=0\)
\(x+y+2=0\)
