Answer
$(-4,-7)$, or $x=-4,\ y=-7,$
The system is consistent, and the lines are independent.
Work Step by Step
$\left[\begin{array}{lll}
x & y_{1} & y_{2}\\
& & \\
-4 & -7 & -7\\
& &
\end{array}\right]$
For $x=-4$, both functions produce a y-coordinate of $-7.$
This means that $(-4,-7)$ is an intersection point, and thus is a solution to the system.
There is only one solution, so the system is consistent, and the lines are independent.
