The equation is y = 1.

y - y_{1} =  \frac{y _{2}-y_{1}  }{ x_{2}-x_{1} } (x- x_{1} )

The points are (-1,1) and (0,1) 
⇒ y-intercept coordinates

y-1 = 1 - 1 (x - -1)
         0 - - 1

y - 1 = 0 (x + 1)
          1

y - 1 = 0

y = 1

If the given data are correct, then the graph overlaps and not parallel, because they have the same slope and y - intercept.  The equation is both y = 1.

The system is consistent but dependent.  The lines are coinciding. The solutions are infinite.
