Hi,

                           

-2x+y=1     (x,y) point (0,1)   and (-1/2,0) on this Line

                           

-4x+2y=-8    (x,y) point (0,-4)   and 2,0) on this Line

Plot points and connect with respective Lines

Lines do not Intersect:  NO solution for this linear system



-2x+y=1  0r  y = 2x+1

-4x+2y=-8

-4x + 2(2x+1) = -8

-4x + 4x + 2 = -8

           2 ≠ -8   NO solution for this linear system
