Let's denote by \(M\) the set of all points in the plane such that their coordinates \(\left[x;y\right]\) satisfy the relation \(2x-y+1=0\). Then, choose the true statement about \(M\).
\(M\) is a line.
\(M\) is a ray.
\(M\) is a finite set of point.
\(M\) is a half plane.

Provided that the missing parts of lines were completed, which of the pictures would depict solution of the system if solved graphically?
\[\begin{aligned}
x-7y&=-9\\
3x-2y&=11\\
\end{aligned}\]

The system of two linear equations can be represented graphically by two lines. Decide which of the pictures corresponds the following system.
\[\begin{aligned}
-x+3y&=3.5\\
1.4x+y&=2.9\\
\end{aligned}
\]
